Breast fat transfer in Switzerland: shaping the breasts with your own fat

Breast fat transfer involves harvesting a little of your own fat from the abdomen, hips or thighs, purifying it, then reinjecting it into the breasts. It allows volume to be moderately increased without an implant, asymmetry to be corrected, a hollow to be filled, the result of an implant augmentation to be improved, or reconstruction after breast cancer to be supported. Its main advantage is a natural result to the touch and to the eye, with a slimmer donor area as a bonus. Its limits lie in the amount of fat available and the part that is resorbed. This page details the indications, technique, number of sessions, safety, imaging follow-up and how things are organised in the Swiss cantons. To compare with implants, see our page on breast augmentation.

Breast fat transfer is usually performed under general anaesthesia, in one to three hours, often as day surgery. The volume gain is about one cup size per session, with some of the fat resorbed during the first few months; two sessions are common. Scars are limited to small incisions of a few millimetres. A return to office work is possible after a few days. Breast imaging is performed before the procedure, and the radiologist must be informed afterwards. Cosmetic fat transfer is at the patient's expense; in reconstruction after cancer, it is covered. Budget guidelines on our page on breast fat transfer prices in Switzerland.

Fat transfer, also called autologous fat grafting or lipomodelling, uses the patient's own fat as a filling material. In the breasts, it has been practised for several decades, first in reconstructive surgery, then in cosmetic surgery, once studies had shown that it did not interfere with breast cancer screening when imaging is correctly interpreted.

Fat injected in small amounts grafts into the breast tissues and acquires a new blood supply there. The part that survives after a few months is lasting and then changes like fat elsewhere in the body, with weight. Fat transfer can be used alone or combined with other procedures: implants, lift, reconstruction.

Women who choose fat transfer often give the same reasons: avoiding an implant and its lifelong surveillance, obtaining a result that does not look like surgery, enjoying a slimmer figure in the donor areas, and keeping a completely natural feel. Some have had implants and no longer want implanted material; others are concerned by the questions raised about implants. For all of them, fat transfer is a gentler option, at the cost of a more limited gain.

Harvested fat is living tissue, made up of fragile fat cells, small vessels and cells capable of transforming. Once injected into the breast, it is no longer connected to any circulation. During the first few days, it survives thanks to fluids from the neighbouring tissues, then new small vessels grow towards it and nourish it. Cells too far from these vessels die and are eliminated.

That is why the injection technique is decisive: tiny deposits, spread in thin layers, all have close contact with well-vascularised tissue. A large deposit of fat, on the contrary, has a centre deprived of blood, which dies and forms a cyst. Survival also depends on the quality of harvesting, preparation, smoking and the recipient's circulation.

Fat is not a mere filling material: it is living tissue, rich in vessels, supporting cells and cells capable of renewing themselves. This explains both its ability to become permanently integrated into the breast and its fragility in the first few weeks, when it must develop a new circulation. It is also what distinguishes it from an implant or an injectable product: once integrated, it is part of you, changes with your body and requires no particular surveillance or replacement. This living nature also explains why lifestyle matters so much after the procedure: a stable weight, not smoking and a good diet help the graft take hold, then stay in place for years to come.

The idea of transferring fat from one part of the body to another dates back to the end of the nineteenth century, with the first fat grafts intended to fill defects. For a long time, results remained unpredictable, with significant resorption. In the 1980s, the rise of liposuction provided an abundant source of fat, but large-volume injections caused cysts and calcifications, which led to great caution regarding the breasts.

In the 1990s, the development of a technique injecting very small amounts in multiple passes transformed the results. Studies then showed that imaging remained interpretable and that the risk of cancer was not increased. Breast fat transfer then became established, first in reconstruction, then in cosmetic surgery.

• "All the fat stays": some of it is always resorbed.
• "You can gain three sizes in one go": the gain per session is limited, often one size.
• "Fat transfer prevents screening": screening remains possible, with an informed radiologist.
• "The fat can migrate": it stays where it was grafted.
• "Fat transfer lifts the breasts": it adds volume; it does not lift the areola.
• "You need to put on weight first": gaining weight for the procedure is not advisable.

Fat transfer is often presented online as a natural augmentation with no constraints, which is partly true but glosses over resorption, the frequent need for two sessions and the after-effects in the donor areas. Favour medical information, the explanations of a qualified surgeon and, for questions about reconstruction, your breast centre team. Testimonials are useful, but every situation is different.

Images of breast fat transfer circulating online sometimes show impressive results, often photographed just after the procedure, when swelling gives a misleading volume, or after several sessions. Rely instead on photos at six months or one year, of women with a body shape close to yours, and on the surgeon's explanations of what is realistic for you.

The choice depends mainly on the desired volume, the fat available and how you feel about implant follow-up. Many women find fat transfer a reassuring compromise, at the cost of a more modest gain. See our page on breast augmentation.

Some injectable fillers, such as hyaluronic acid, have been offered to enlarge the breasts without surgery. Plastic surgery and radiology societies advise against them: they can form nodules, migrate, seriously hinder the interpretation of mammograms and ultrasounds, and delay the diagnosis of a lesion. Other so-called permanent products injected in the past have left serious complications that are difficult to treat.

Autologous fat, by contrast, is living tissue that integrates into the breast and whose appearance on imaging is well known to radiologists. It is the only injectable substance recognised for enlarging the breasts safely.

• She wants a moderate volume gain, of one to two sizes, with a very natural result.
• She has fat on the abdomen, hips or thighs that she would like slimmed.
• Her weight is stable.
• She does not smoke, or agrees to stop.
• Her breasts are not clearly sagging, or she accepts a combined lift.
• She accepts the possibility of two sessions and some resorption.

The surgeon assesses these criteria at the consultation and may propose an alternative if fat transfer alone cannot achieve the goal.

Fat transfer alone is less suitable for very slim women, who lack fat to harvest, for those who want a large volume gain in a single procedure, or for those whose breasts are clearly sagging and who do not want a lift. It is also less indicated in smokers, whose fat survival is reduced. In these situations, an implant, a hybrid technique or a lift may be preferable. An honest surgeon will tell you so.

• When the volume or shape of your breasts bothers you and you prefer to avoid an implant.
• If an asymmetry shows under clothes.
• If the edges of your implants are becoming visible.
• If you are considering having your implants removed.
• After breast cancer, to improve a reconstruction or a treated breast.
• Simply to find out your options, without commitment.

An information consultation lets you find out whether fat transfer suits your situation and understand its limits.

Some very slim women consider deliberately gaining weight to have more fat available. This strategy is generally not advised: fat gained quickly and then lost after the procedure will reduce breast volume, as grafted fat follows weight changes. If the available fat is insufficient, a small-volume implant, possibly as a hybrid technique, is often a better solution.

• Élodie, 32, wants one size more, fat on the hips: two fat transfer sessions six months apart.
• Sonia, 28, one-size asymmetry: one session on the smaller side.
• Laure, 41, implants visible in the upper breast: covering fat transfer.
• Martine, 55, removal of old implants: explantation, lift and fat transfer.
• Claire, 46, after breast-conserving cancer treatment: filling of the hollow in two sessions, covered by insurance.
• Lina, 24, tuberous breasts: release of the constricting bands and fat transfer, three sessions.
• Nora, 35, very slim: insufficient fat, directed towards a hybrid augmentation.
• Jade, 30, trans woman: fat transfer to widen the base and soften the cleavage.

Volume asymmetry between the two breasts is one of the best indications for fat transfer. More fat is injected on the smaller side, allowing a fine adjustment that is impossible with two standard-size implants. When the difference is significant, two sessions may be needed. Fat transfer can also be combined with a reduction or an implant on the other side. Asymmetry in the shape or height of the areolas sometimes requires an additional procedure.

Many women mainly want a fuller upper breast and a more harmonious cleavage, without necessarily increasing overall volume much. Fat transfer is particularly suited to this goal: the fat can be placed precisely in the upper breast and the space between the breasts, where an implant cannot act finely. The cleavage nevertheless remains limited by the position of the muscle attachments on the breastbone: it cannot bring the breasts closer together beyond their anatomy.

Fat transfer is not only used to increase volume. It can also change the shape of the breast: rounding a narrow lower breast, filling a hollow upper pole, softening an abrupt transition between the breast and the chest, correcting a localised depression. This precision is one of its strengths, particularly for asymmetries of shape and the after-effects of previous surgery.

Chest asymmetry, linked to scoliosis or a difference in rib shape, can make one breast look larger or more projected than the other. Fat transfer allows these differences to be finely corrected by injecting fat on the less projected side, including outside the breast, on the chest itself. This is an advantage over implants, which cannot correct a chest depression outside the breast.

Tuberous breasts have a narrow base, a high fold and an underdeveloped lower breast, sometimes with a wide, puffy areola. Fat transfer is particularly useful for widening the base and filling the lower breast, often combined with small internal incisions that release the fibrous bands responsible for the tube shape. The fold can be lowered and the areola reduced. Results are natural, at the cost of several sessions in marked forms. These corrections may be the subject of a request for coverage.

In tuberous breasts, the gland is constricted by fibrous bands that prevent it from developing downwards and to the sides. The surgeon releases these bands with small internal incisions made with a needle or cannula, allowing the breast to spread. They then inject fat into the lower part to round it and lower the fold. When the areola is wide and puffy, a reduction with a scar around the areola is combined. Several sessions are often needed, but the result is natural and lasting.

In slim women, the skin and gland covering an implant may be too thin: the edges of the implant show in the upper breast, and folds appear at the sides or when leaning forward. Fat transfer thickens this coverage by injecting a layer of fat under the skin, without touching the implant. It also improves the cleavage and the transition between the upper breast and the chest. It can be performed when the implant is placed or later.

In hybrid augmentation, fat transfer complements a moderate-volume implant. It is injected into the areas where the implant risks showing: the upper cleavage, the space between the breasts, the sides. It allows a slightly smaller implant to be chosen and a more natural contour to be achieved, particularly in slim women. The fat is injected under the skin, avoiding contact with the implant. See our page on hybrid breast augmentation.

More and more women choose to have their implants removed after years, out of a wish for an implant-free body, because of a complication or because of symptoms they attribute to them. After removal, the breasts often look empty and the skin lax. Fat transfer restores natural volume, often combined with a lift to raise the breasts. It can be performed at the time of explantation or a few months later, once the tissues have stabilised. See our page on implant removal with a lift.

Some women want to have their implants removed because of symptoms they attribute to them, such as fatigue or diffuse pain. Removal, often combined with capsule removal, can be complemented by fat transfer to avoid breasts that look too empty. It is important to discuss these symptoms openly, also looking for other possible causes, and to keep realistic expectations: some women feel better after removal, others do not. Fat transfer allows harmonious breasts to be kept without implanted material.

A lift raises the breasts and removes excess skin, but does not create volume; the upper breast may remain empty. Fat transfer ideally complements the lift by filling the upper pole, naturally and without an implant. It can be performed during the lift, for small volumes, or a few months afterwards, for better control of fat survival. See our page on the breast lift.

Fat harvesting is already a form of liposuction, but it is generally limited to the amount needed for the breasts. Some women want to take advantage of the procedure for more extensive liposuction, to clearly slim the abdomen, hips or thighs. The two goals are compatible: the surgeon harvests the best-quality fat for the breasts, then completes the liposuction. The procedure is a little longer and recovery of the suctioned areas more marked. See our page on breast fat transfer with liposuction.

Some women want to shape both their breasts and their buttocks with their own fat. This is possible if the amount available is sufficient, which implies a figure with significant fat reserves. Buttock fat transfer follows strict safety rules, notably injection under the skin only, to avoid the risk of fat embolism. The surgeon assesses whether both goals are compatible in a single procedure or whether it is better to separate them.

After pregnancies, many women want to restore both the breasts and the abdomen. Breast fat transfer can be part of a broader programme combining liposuction, abdominoplasty or a breast lift, performed in one or more procedures. The fat harvested from the abdomen and hips then fills the breasts. The surgeon assesses the safety of a combined procedure according to your health and the planned duration. See our page on the mommy makeover.

After one or more pregnancies and breastfeeding, the breasts often lose volume, particularly in the upper breast. If the areola remains above the fold, fat transfer can restore a natural contour without an implant. It is often combined with liposuction of the abdomen or hips, areas where fat has settled after pregnancies. It is advisable to wait at least six months after weaning and, ideally, to have completed your plans for pregnancy. If the breasts are sagging, a lift is combined.

A pregnancy after fat transfer proceeds normally. The gland develops under the effect of hormones, then decreases after breastfeeding; the grafted fat, for its part, varies with the weight gained and lost. The result may therefore change. Breastfeeding is possible, as the fat does not affect the gland or the ducts. If the volume has decreased after pregnancy, an additional session can be considered later.

Fat transfer prevents neither pregnancy nor breastfeeding. However, pregnancy and breastfeeding change the breasts and weight, which may make the result vary. If you plan to have children soon, it may be preferable to wait, so that breasts that will have changed can be corrected in one go. If you wish to have it beforehand, an additional session can be considered later. Both choices are legitimate.

Breastfeeding is not affected by fat transfer, as the fat is injected around the gland and not into the ducts. Milk production and nipple sensation generally remain normal. During breastfeeding, the breasts change in volume; after weaning, the grafted fat remains, but the gland decreases, which may slightly change the shape. An additional session can be considered later if necessary.

At menopause, the gland decreases and the breasts become softer, often fattier, sometimes emptied at the top. Fat transfer can restore volume to the upper pole and cleavage naturally. The skin, which is more supple, often accepts the fat well. A recent mammogram is essential before the procedure, and radiological follow-up continues with an informed radiologist. If the breasts are sagging, a lift is combined.

In young women, fat transfer is attractive for its natural appearance and the absence of an implant to monitor for decades. It suits those who have a little fat and want a moderate gain, or correction of asymmetry. Very slim young women, however, often lack fat; the firm skin of small breasts also limits the amount that can be injected per session. The surgeon honestly assesses whether the goal is achievable.

For sportswomen, fat transfer has several advantages: no implant that could move when the pectorals contract, a quick recovery and a moderate volume compatible with running and high-impact sports. Very lean sportswomen, however, often have little fat. Intensive training can also reduce the volume obtained if it leads to weight loss. Schedule the procedure outside competition periods.

After breast cancer, fat transfer has become a major reconstruction tool. After a mastectomy, it improves the shape, softness and coverage of a breast reconstructed with an implant or flap, by filling hollows, softening contours and hiding the edges of the implant. After breast-conserving treatment, it fills the deformity left by removal of the tumour and radiotherapy.

In some cases, the breast can be reconstructed with fat alone, over several sessions. These procedures are performed in liaison with the oncology team, after a waiting period defined by the team, and are covered by basic insurance. Oncological and radiological follow-up continues as normal.

After complete removal of a breast, reconstruction can be performed with an implant, with a flap — that is, with tissue taken from elsewhere on the body — or with fat alone in some cases. Fat transfer is often used as a complement: it fills hollows under the collarbone and at the sides, thickens implant coverage, softens the contour of a flap and improves skin softness. Several sessions, a few months apart, are common.

When reconstruction is performed with fat alone, it requires several sessions, sometimes preceded by external expansion, and a sufficient amount of fat. It avoids any implant and gives a soft, natural breast.

After removal of a tumour with conservation of the breast, followed by radiotherapy, the breast may be left with a hollow, asymmetry or retracted skin. Fat transfer gradually fills the deformity and improves the softness of the irradiated tissues. It is performed after a waiting period defined by the oncology team, generally once treatment is complete and check-ups are reassuring. Recent imaging is essential before each session.

In Switzerland, certified breast centres, often attached to university and cantonal hospitals, bring together gynaecologists, oncologists, radiologists, radiotherapists and plastic surgeons. For reconstructive fat transfer, they coordinate oncological follow-up, imaging and surgery, and facilitate coverage procedures. They are often the most appropriate point of contact after cancer.

After reconstruction, the other breast can be adapted to restore symmetry: by fat transfer if it is smaller, by reduction or a lift if it is larger or sagging. These procedures are part of the reconstruction and are covered by basic insurance. They are generally performed once the reconstruction has stabilised.

Reconstructive fat transfer is often part of a long journey: several sessions a few months apart, possibly combined with other procedures, such as placing or exchanging an implant, areola reconstruction or symmetrisation. It sometimes takes one to two years to achieve the final result. This time allows the tissues to stabilise between each stage and generally gives better results. The team supports you throughout this journey.

Once the volume and shape of the reconstructed breast are satisfactory, the areola and nipple can be reconstructed with a small graft or a local flap, then by medical tattooing of the areola. Fat transfer can improve skin softness in this area. These steps, covered in reconstruction, complete the result and contribute greatly to the feeling of having a whole breast again.

The journey after breast cancer is gruelling, and reconstruction is often an important step in regaining your self-image. Breast centres frequently offer psychological support, specialist nurses and support groups. These resources can help you through the stages of reconstruction, including fat transfer sessions, and in living with the changes to your body.

Radiotherapy, essential in many breast cancer treatments, often leaves the skin firmer, less elastic, sometimes painful, with less well vascularised tissues. These changes complicate implant reconstruction. Fat injections into these tissues seem to improve their softness and blood supply and reduce some pain. Fat transfer can thus prepare the ground for later reconstruction or improve an existing reconstruction.

Thick, retracted or adherent scars, after breast surgery or an injury, can be improved by small injections of fat or microfat under the scar. The fat releases adhesions, adds volume under hollows and seems to improve skin softness and appearance. This indication is common in reconstruction and can complement volume fat transfer.

When fat transfer began to be used in reconstruction, a question arose: could grafted fat, rich in active cells, promote cancer recurrence? The many studies conducted since have not shown an increased risk of recurrence after reconstructive fat transfer, when the recommended waiting periods are respected. In cosmetic surgery, no increase in the risk of breast cancer has been demonstrated.

As a precaution, fat transfer is performed after imaging, and the usual oncological and radiological follow-up is maintained. Women with a genetic predisposition or a personal history are the subject of specific discussion.

Poland syndrome combines, on one side, partial or total absence of the pectoralis major muscle, often an underdeveloped or absent breast, and sometimes hand abnormalities. Fat transfer gradually fills the hollow under the collarbone and rebuilds a harmonious breast, alone or combined with an implant. Several sessions are generally needed. This congenital malformation may be covered by insurance.

Pectus excavatum, with a sunken breastbone, or naturally hollow cleavage can be improved by fat transfer, which fills the depression between the breasts. Several sessions are often needed for significant depressions. Severe forms of pectus excavatum may call for other treatments, notably orthopaedic or a custom-made implant; the surgeon assesses the best option.

In trans women, feminising hormone therapy develops the breasts over one to two years, often modestly. Fat transfer can complement this development, particularly to widen the breast base and soften the cleavage, or be combined with an implant for greater volume. The amount of fat available is sometimes limited in slim patients. Coverage may be requested as part of a gender dysphoria care pathway.

Cosmetic fat transfer is not offered before breast development is complete. In adolescents with a significant malformation, such as marked tuberous breasts, major asymmetry or Poland syndrome, treatment can be discussed once growth is complete, often at around seventeen or eighteen, with parental consent and after careful assessment. Fat transfer is then often preferred to implants, as it adapts well to breasts that may still change and does not require future implant exchange.

In men, chest fat transfer is rarely used to enlarge the chest, but it can correct asymmetry after gynaecomastia surgery, fill a hollow after an injury or improve the appearance of a sunken chest. It can also accompany reconstruction of an absent pectoral muscle in Poland syndrome. Gynaecomastia itself, on the contrary, is treated with liposuction and removal of the gland. See our page on gynaecomastia.

Harvesting begins with infiltration, through small incisions, of a solution containing a local anaesthetic and adrenaline, which reduces bleeding and makes suction easier. The surgeon then suctions the fat with fine cannulas at low vacuum, with regular movements, to avoid damaging the cells. They spread the harvesting over the area so as not to create hollows.

The choice of areas combines two goals: having enough good-quality fat, and slimming the figure where you want. The abdomen, hips and inner thighs are the most common areas. The incisions, a few millimetres long, are placed in natural creases.

The surgeon proposes the areas according to your figure, the amount of fat needed and your preferences. Several areas are often combined.

To achieve a gain of about one size, it is often necessary to inject two hundred to three hundred millilitres of purified fat per breast, which requires harvesting more, since preparation eliminates some of the fluid and oil. For both breasts, the total amount harvested thus often reaches several hundred millilitres, sometimes a litre or more. These figures vary greatly depending on body shape and goal; the surgeon estimates them at the consultation.

Fat harvested from different areas does not have exactly the same properties: some areas, such as the abdomen or inner thighs, provide soft fat that is easy to harvest; others, such as the back, more fibrous fat. Studies do not identify a clearly superior area for graft survival. The choice is therefore made mainly according to the amount available and the desired figure. Fat from diet-resistant areas, such as the saddlebags, tends to remain stable.

Before the procedure, the surgeon estimates the amount of fat needed based on the desired gain, expected resorption and the capacity of the breasts. They also assess the amount available by pinching the skin of the donor areas and observing the figure. During the procedure, they measure the volumes harvested and injected on each side, which allows symmetry to be adjusted and these data to be recorded in the operative report, useful for a second session.

After suction, the fat contains infiltration fluid, blood and oil from damaged cells, which must be removed in order to inject concentrated tissue. Several methods exist: decanting, where the fat separates naturally by gravity; washing and filtration through membranes; and gentle centrifugation, which separates the layers in a few minutes. Each method has its supporters.

Studies do not identify a clearly superior method; what matters is handling the fat as little as possible, keeping it away from air and heat, and injecting it quickly. Some closed systems, designed for large volumes, allow the fat to be processed in a closed circuit.

For certain indications, the surgeon can refine the harvested fat by passing it through very fine filters. Microfat, made of small fragments, is used for delicate areas and thin skin, for example around the areola or the cleavage. Nanofat, even finer, contains almost no living fat cells but regenerative cells; it is used to improve the quality of the skin and scars rather than to add volume. These variants complement conventional fat transfer.

Reinjection is the step that most determines the result. The surgeon uses fine, blunt-tipped cannulas introduced through small incisions around the breast. They deposit the fat while withdrawing the cannula, in fine trails of a few drops, at different depths: under the skin, around the gland, sometimes in front of or within the pectoral muscle. They vary the directions to create a dense network of small deposits rather than clumps.

They do not try to inject the maximum: beyond a certain pressure in the tissues, the fat survives less well. They regularly check volume, shape and symmetry, lying down and then semi-sitting.

The surgeon distributes the fat in several layers of the breast. The layer under the skin gives softness and hides irregularities; the layer around the gland, without injecting into the gland itself, adds volume; the layer in front of or within the pectoral muscle, which is well vascularised, often receives a good part of the graft and fills the upper breast. This distribution multiplies the contact surfaces with vascularised tissue and improves survival.

Injection into the gland itself is avoided, as it could complicate the interpretation of imaging and fat survives less well there.

It is tempting to think that injecting a lot of fat would be enough to obtain a large volume. But each breast has a limited capacity, determined by skin elasticity and the space available between tissues. Beyond that, pressure increases, small vessels are compressed and a greater proportion of fat dies, with more cysts. The surgeon stops when the tissues are filled without excessive tension. That is why large volume gains require several sessions.

To improve fat survival, some teams enrich the graft with regenerative cells extracted from part of the harvested fat, or add platelet-rich plasma. These approaches are promising in research, but their real benefit in routine practice remains debated, and some cell manipulations are strictly regulated.

If you are offered an expensive enrichment technique, ask what studies it is based on, what concrete benefit it brings and what its regulatory framework is. A well-mastered conventional technique already gives very good results.

Before major fat transfer, some centres offer a device consisting of shells connected to a small pump, worn for several weeks, which creates a slight vacuum on the breasts. This external expansion gradually stretches the skin and increases the blood supply, which allows more fat to be injected and improves its survival. It requires wearing the device for many hours every day, often at night, with great diligence. It is mainly used in reconstruction and for very small, firm breasts.

The number of sessions depends on the goal. To fill a hollow, correct a small asymmetry or hide the edges of an implant, one session is often enough. For an augmentation of one size, one session may be enough in a woman with supple skin; for two sizes or more, two sessions are common. In reconstruction, three or more sessions are sometimes needed.

Sessions are spaced at least three months apart, ideally six, to let the fat stabilise and allow the volume actually obtained to be judged. Each session benefits from the previous one: tissues already enriched with fat and better vascularised accept the new graft better.

Fat transfer lends itself well to a gradual approach: a first moderate session, then a second if you want more volume. This approach lets you discover your new body in stages and adjust the result to your wishes. Some women stop after one session, happy with a discreet change; others continue. There is no obligation: you decide at each stage, after seeing the result of the previous one and discussing it with your surgeon at the three- or six-month check-up.

Resorption is the decrease in volume that follows fat transfer. It has two components: the disappearance of swelling in the first few weeks, which at first makes the breasts larger than the final result, and the elimination of the part of the grafted fat that did not survive. This second part varies according to technique, fat quality, breast circulation, smoking and early physical activity.

The surgeon anticipates resorption by injecting slightly more than the desired volume, within the limits of what the tissues accept. It is important not to be disappointed by the decrease in volume in the first few weeks: it is expected.

Fat transfer results vary from one woman to another. Those with supple skin, breasts already somewhat developed, plenty of fat, a stable weight and who do not smoke generally keep a greater proportion of fat. Conversely, very small, firm breasts, tight skin, smoking or weight loss after the procedure reduce the gain. The surgeon's technique also plays an important role.

Fat transfer requires patience: the volume decreases after the first few weeks, stabilises at around three to six months, and any second session requires a few more months. Between the first consultation and the final result, six months to a year is often needed. Women who accept this pace are generally the most satisfied, as they judge the result at the right time.

The two breasts do not always react in the same way: resorption may be slightly greater on one side, because of a difference in blood supply, skin suppleness or the way the fat was distributed. This sometimes results in a small asymmetry after a few months. It is corrected at a second session by injecting more on the side that kept less.

Gains are often described in cup sizes, but this notion is approximate. One cup size corresponds to an increase of about two centimetres in the bust measurement at nipple level, which represents a different volume depending on the band size. For a slim woman with a narrow band size, one size corresponds to a smaller volume than for a woman with a wide band size. That is why surgeons think rather in millilitres and shape, and gain estimates remain indicative.

Fat transfer gives natural, appreciated results, but it does not turn very small breasts into generous ones in a single session. A gain of one size per session is a realistic goal for most women. It does not lift sagging breasts and does not guarantee perfect symmetry. The most satisfied patients are those who sought a subtle, natural change and had accepted the idea of two sessions.

At the consultation, the surgeon asks about your expectations, medical history, pregnancies, weight and family history of breast cancer. They examine the breasts, measure them, assess skin suppleness, the position of the areolas and any asymmetry. They also examine the possible donor areas and estimate the amount of fat available.

They explain the likely gain, the number of sessions, resorption, recovery, risks and imaging follow-up. They prescribe a mammogram or ultrasound if necessary and give you a quote. A second consultation allows the plan to be confirmed.

• The amount and distribution of available fat.
• The suppleness of the breast skin, which limits the volume that can be injected.
• The shape, volume and symmetry of the breasts.
• The position of the areolas and any descent.
• The quality of the skin in the donor areas.
• Your personal and family history of breast cancer.
• Your smoking, your weight and its stability.
• Your expectations and your availability for two sessions.

These elements allow a realistic gain to be estimated and, if needed, a more suitable alternative to be proposed.

• Bare-chested, standing, arms by your sides: front, both profiles, three-quarter views.
• A photo from the front and in profile of the areas where you have a little fat.
• Daylight, light background, no filter.
• A few words about the desired volume and your medical history.

These photos allow the surgeon to estimate the available fat and the realistic gain, before an in-person consultation.

A second consultation before the first session allows you to revisit the desired volume, confirm the donor areas, go through the consent form and quote, and ask questions that have come up in the meantime. It is also an opportunity to discuss the timing of sessions and any second session. You can bring a trusted person with you.

• Can fat transfer alone achieve the volume I want?
• How many sessions do you plan, and at what interval?
• How much resorption should I expect?
• Where will you harvest the fat, and what effect will it have on my figure?
• Which fat preparation method do you use?
• How many breast fat transfers do you perform each year?
• What imaging follow-up do you recommend?
• What are the financial conditions for a second session?

Smoking is the enemy of fat transfer. Nicotine constricts small vessels and carbon monoxide reduces the oxygen carried by the blood, while grafted fat depends entirely on the formation of new vessels to survive. In smokers, resorption is greater and cysts more frequent. Stopping completely several weeks before and after the procedure, including e-cigarettes, is strongly recommended.

Mention all your treatments, supplements and herbal products. Aspirin, certain anti-inflammatories, omega-3s or ginkgo encourage bruising; whether to stop them is decided with the doctor. Anticoagulants are never stopped without the prescriber's advice. Poorly controlled diabetes, an autoimmune disease or a treatment that modifies immunity can reduce fat survival and increase the risk of infection. Hormonal contraception is discussed with the anaesthetist.

Before any breast fat transfer, a clinical examination and imaging are performed according to your age and history: mammogram, ultrasound, sometimes MRI if there is a high family risk. These examinations check that there is no lesion before the procedure and serve as a reference for interpreting future examinations. Keep them and bring them to your next screening appointments.

• Prepare loose clothes that do not squeeze the breasts or the donor areas.

You arrive having fasted. With you standing, the surgeon marks the donor areas and the areas to be filled on the breasts. After the anaesthetic, they infiltrate and harvest the fat, prepare it, then reinject it into the breasts. The procedure takes one to three hours. At the end of the procedure, the donor areas are covered with dressings and a compression garment, and the breasts with a soft bra.

You generally go home the same evening, accompanied. The donor areas often ooze a little in the first few hours: this is the infiltration fluid draining away.

Breast fat transfer is usually performed as day surgery: you arrive in the morning and go home in the evening, accompanied. A night at the clinic may be offered if harvesting is very extensive, if a procedure is combined, or if you live alone. Before discharge, the team checks your pain and your ability to walk, drink and pass urine, and gives you written instructions and the number to call.

Breast fat transfer is usually performed under general anaesthesia, as it involves both harvesting, sometimes from several areas, and injection into both breasts. For a small correction, such as covering an implant or a limited hollow, local anaesthesia with sedation may be enough. The anaesthesia consultation assesses your health, treatments and risk of thrombosis.

• What type of anaesthesia is planned, and how long will it last?
• Do I need to stop my pill or certain medicines?
• What measures are planned against thrombosis?
• How will pain in the donor areas be treated?
• What if I am prone to nausea after anaesthesia?

Fat transfer leaves only small incisions of three to five millimetres: on the donor areas, often in natural creases such as the navel or the groin, and around the breasts, in the fold under the breast or at the edge of the areola. They are pink for a few weeks and then fade. On darker skin, they may remain slightly pigmented for longer; sun protection helps.

The donor areas are the most tender, as after liposuction: aching, a burning sensation, spreading bruises. The breasts are swollen and slightly tight. Simple painkillers are generally enough. Walk regularly from the evening or the next day, sleep on your back, and wear the compression garment day and night and the soft bra.

Avoid compressing the breasts at all costs: no tight bra, no lying on your front, no massage. Showering is generally allowed after twenty-four to forty-eight hours.

The first few weeks after fat transfer are often marked by a contrast: swollen breasts, larger than hoped, then a gradual decrease that can be worrying. Meanwhile, the donor areas are painful, bruised and firm before slimming down. Knowing in advance that these stages are normal helps you get through them calmly. Bear in mind that the result is judged after three to six months, and note your questions for the check-ups.

Fat transfer generally preserves sensation in the breasts and areolas, as the injections are made with fine cannulas that push nerves aside rather than cutting them, and the fat is not injected into the gland. A slight temporary change, numbness or tingling, may occur in the first few weeks, linked to swelling. It usually disappears within a few weeks. It is an appreciated advantage compared with some other breast procedures.

Pain after breast fat transfer comes mainly from the donor areas: a feeling of intense aching, burning or bruising, especially when getting up, sitting down or bending. It is greatest in the first two or three days and decreases markedly within one to two weeks. The breasts are rather tight and tender. Simple painkillers, taken regularly at first, the compression garment and gentle walking bring relief. Increasing pain, with redness or fever, requires medical attention.

Bruising is common and sometimes extensive on the donor areas, particularly the thighs and abdomen. It changes from purple to yellow within two to three weeks. Stopping certain medicines and supplements before the procedure, on medical advice, and wearing the compression garment reduce its extent. On the breasts, bruising is generally more discreet. Some ointments can help it fade.

After harvesting, the skin of the suctioned areas may be numb, tingling or, conversely, hypersensitive for several weeks, until the small nerves repair. A feeling of a stiff area or small nodules under the skin is also common and gradually disappears. On the breasts, sensation is rarely changed. These sensations are normal; report them if they persist beyond a few months.

In the first few weeks, choose loose clothes that are easy to pull on over the compression garment, and tops that do not squeeze the breasts. Flowing dresses and trousers are more comfortable than tight jeans over suctioned thighs or hips. Soft bras without underwiring or padding are suitable. After about a month, you can gradually return to your usual clothes, often with the pleasure of a slimmer figure.

Swimming is possible once the small incisions have closed, generally after one to two weeks. Avoid direct sun on bruised areas and incisions for several weeks, so as not to encourage pigmentation. Very hot baths and saunas are not advised in the first month. After that, no particular precautions: grafted fat is not affected by water, sun or heat.

After harvesting, a compression garment is worn on the suctioned areas, day and night in the first few weeks, then during the day, often for three to six weeks. It limits swelling and bruising, helps the skin retract and reduces the risk of irregularities. It must be well fitted, without compressing excessively or creasing. On the breasts, by contrast, any compression is avoided: a soft bra without underwiring is worn for comfort, without squeezing the grafted fat.

The suctioned areas are often more uncomfortable than the breasts: aching, a burning sensation, bruising, swelling, sometimes numbness of the skin. These sensations decrease within two to three weeks. Gentle massage or lymphatic drainage, advised by the surgeon after a few days, helps soften the tissues and reduce swelling. Temporary firmness, a feeling of a stiff area, is common and disappears within a few weeks to a few months.

A few days after the procedure, some surgeons recommend manual lymphatic drainage sessions on the donor areas. Performed by a trained physiotherapist, this gentle massage helps clear swelling, reduces bruising and firmness, and improves comfort. It is not performed on the breasts in the first few weeks, so as not to displace the grafted fat. Ask the surgeon's advice before starting. These sessions can be prescribed and, depending on the situation, covered when they are part of a reconstruction.

Harvesting that is too superficial, too extensive or poorly distributed can leave irregularities: small hollows, bumps or rippling of the skin, especially on the abdomen and inner thighs. Experienced surgeons spread the suction in a fan pattern, at depth, and do not harvest more than necessary. The compression garment and massage help the skin retract evenly. A persistent irregularity can be corrected after a few months, sometimes with a small fat transfer to the area.

• Wear the compression garment on the donor areas.
• Do not compress the breasts: no underwiring, no lying on your front.
• Walk every day, without intense sport.
• Avoid saunas, hot baths and sun on the incisions.
• Do not smoke.
• Keep a stable weight.
• Report any fever, redness or unusual pain.

The instructions given after fat transfer have a precise purpose: protecting the grafted fat while it develops its new blood supply. Not compressing the breasts, not smoking, not losing weight, avoiding excessive heat and knocks: each of these precautions improves graft survival. Following them carefully during the first month is an integral part of the treatment.

Grafted fat retains the memory of its origin: it behaves like fat from the area it came from, and varies with weight. Significant weight loss after fat transfer reduces breast volume; weight gain increases it. Above all, avoid losing weight in the first few months, when the fat is integrating. A stable weight is the best guarantee of a lasting result.

After fat transfer, it is advisable to keep a stable weight, without watching the scales obsessively. Small variations of one or two kilos have little effect. It is mainly significant weight loss, through strict dieting or illness, that reduces the volume obtained. A balanced diet and regular physical activity are generally enough to preserve the result.

Once recovery is over, fat transfer imposes no particular constraints: no implant check-ups, no sporting restrictions, no precautions when travelling or having examinations. The breasts live and change like natural breasts. You simply need to keep a stable weight, continue the usual screening and mention the procedure to radiologists. This freedom is one of the arguments most often cited by women who have chosen this technique.

Grafted fat that has survived is lasting: check-ups after several years show stable volume in women whose weight has not changed. It then follows the body's changes: it increases with weight gain, decreases with weight loss, and the breasts age naturally with the skin and gland. Unlike an implant, it does not rupture and does not cause capsular contracture. The result therefore ages like breasts that have not been operated on, with a little more volume.

Walking is advised from the first few days. Gentle sport resumes after two weeks, intense sport after three to four weeks, depending on how tender the donor areas are. During the first month, avoid activities that strongly compress the breasts or make them bounce, and wear a soft sports bra that supports without squeezing. After that, no particular restrictions: grafted fat is not affected by sport or weight training.

For about four weeks, sleep on your back so as not to compress the breasts. If the donor areas are on the hips or thighs, a pillow between the knees or under the legs improves comfort. Sleeping on your front is not advised during the first month, while the grafted fat develops its new blood supply.

During the first few weeks, grafted fat is fragile. Intense cold applied to the breasts could reduce the circulation needed for its survival; it is generally avoided on the breasts, but can be used on the donor areas. Excessive heat, such as saunas or very hot baths, increases swelling and is not advised for a few weeks. Sunbathing on the small incisions should be avoided until they have healed.

For office work, a return is often possible after three to seven days, depending on the extent of the donor areas and how comfortable you are sitting. The compression garment can be worn discreetly under clothing. Physical jobs, which require carrying loads, bending or standing for long periods, often need two to three weeks. Working from home makes a gradual return easier. The sick note does not mention the nature of the procedure.

Fat transfer shows little during recovery: the breasts are slightly swollen, but bruising is mainly on the donor areas, hidden by clothing. The compression garment can be worn discreetly. Most women resume a normal social life after a few days, avoiding intense physical activity. Nothing obliges you to specify the nature of the procedure; the sick note does not mention it.

Working from home often allows you to resume activity after a few days, alternating sitting and standing to relieve the donor areas, particularly if the fat was harvested from the thighs or buttocks. A soft cushion helps you sit comfortably. Get up regularly to walk, which also reduces the risk of thrombosis. Fatigue in the first few days is normal.

Driving generally resumes after a few days, when sitting and moving your legs are no longer painful, you can brake suddenly without discomfort and you are no longer taking medicines that cause drowsiness. The seat belt must not compress the breasts; a small cushion can improve comfort.

Short journeys are possible after a few days. For a long trip, particularly by plane, wait at least one to two weeks and ask the surgeon's advice, because of the risk of thrombosis after liposuction. Wear the compression garment, drink enough and get up regularly to walk. Avoid sunbathing and swimming until the small incisions have closed.

Intimate life can resume after one to two weeks, depending on the comfort of the donor areas, avoiding any pressure on the breasts for about a month. Breast sensation is rarely changed, as the injections are made with fine cannulas. Many women appreciate the natural feel of their breasts after fat transfer.

In the first few days, help is useful for tasks that strain the donor areas: bending, carrying, looking after children. Those close to you should know that extensive bruising on the abdomen or thighs is normal, but should know the warning signs: fever, spreading redness, breathlessness, chest pain, a swollen calf. Their patience also matters during the months when breast volume is stabilising.

Fat transfer is often discreet: those close to you notice a slightly slimmer figure and more harmonious breasts, without always identifying what has changed. You have no obligation to justify your choice. Talking to a trusted person can nevertheless help organise recovery and get through the period when breast volume is changing.

If a friend or relative is considering breast fat transfer, share the essential points with her: carefully check the surgeon's qualifications, understand that the gain per session is moderate and that some of the fat is resorbed, plan for a possible second session, keep a stable weight, stop smoking, and inform the radiologist at examinations. Encourage her to take her time and ask all her questions.

• "Is it really your fat?" Yes, harvested from the abdomen, hips or thighs.
• "Does it last?" The fat that has survived after a few months stays in place.
• "Why not implants?" For a natural result, with no implant to monitor.
• "Did it hurt?" Mainly where the fat was harvested.
• "Will you have to do it again?" Sometimes a second session to reach the desired volume.

As fat transfer is usually day surgery, someone must take you home and, ideally, you should not be alone on the first night. Prepare simple meals, loose clothes, a spare compression garment and your medicines in advance. Everyday tasks remain possible, avoiding compressing the breasts and carrying loads.

Young children who climb onto your lap or snuggle against your chest can press on painful donor areas and compress the breasts. Arrange help for the first few days, and explain to the children that they need to be careful for a while. After one to two weeks, family life resumes its course, taking care of the breasts for up to a month.

• A check-up after one week: incisions, bruising, compression garment.
• A check-up at around six weeks: resuming activities, volume changes.
• A check-up at three months: estimate of the fat retained.
• A check-up at six months: final volume, decision on a second session.

Between appointments, report any unusual sign. After the last session, reference imaging is often recommended for women of screening age.

The donor areas deserve as much attention as the breasts at check-ups. The surgeon checks the healing of the incisions, the absence of haematoma or infection, the evenness of the skin and the evolution of firmness. They adjust how long the compression garment is worn and the massage. If an irregularity appears, it is monitored and can be corrected after a few months.

A year after the last session, a review allows the final volume, symmetry, breast softness and the appearance of the donor areas to be assessed. It is also the time to take stock of imaging and check that the radiologist has information about the procedure. After that, no particular follow-up is needed beyond the usual screening.

The result of fat transfer is judged after three to six months, once the swelling has gone and resorption is complete. Compare photos taken before and after in the same lighting and posture, rather than your impressions in the first few weeks, which are distorted by swelling. Also look at the figure in the donor areas, which is part of the benefit. If the volume suits you, nothing more is needed; otherwise, a second session can be discussed.

Studies on breast fat transfer show high satisfaction, particularly for the natural character of the result and the slimming of the figure. They confirm that some of the fat is resorbed, to a degree that varies with techniques and patients, and that small benign images on mammograms are common but well recognised by experienced radiologists. In reconstruction, they have not shown an increased risk of cancer recurrence when the recommended waiting periods are respected. Serious complications are rare.

Breast fat transfer has been the subject of many studies and of recommendations from learned societies in plastic surgery and radiology. This work has clarified its indications, technical rules, safety with regard to screening and, in reconstruction, oncological risk. It is now considered a standard technique, taught and practised in university departments as well as in private practice. Research continues to improve fat survival and the predictability of the result.

Plastic surgeons now consider fat transfer an indispensable tool, in both cosmetic surgery and reconstruction. They highlight its strengths — naturalness, no implant, a slimmer figure — but also its limits: moderate gain, variable resorption and the frequent need for several sessions. They stress the importance of good patient selection, rigorous technique and realistic expectations as the conditions for a satisfying result.

A second session is decided after at least three months, ideally six, when the volume obtained is stable. The surgeon assesses the fat still available, often in different areas from the first time, and the suppleness of the breasts, generally better thanks to the first graft. The second session proceeds like the first, with similar recovery. It allows volume and symmetry to be refined.

Sometimes the volume obtained is lower than hoped, an asymmetry persists or a donor area shows an irregularity. Before judging, wait at least three to six months. Then talk frankly to the surgeon about what bothers you. A second fat transfer session, a small touch-up of the donor area, or adding an implant as a hybrid technique may be proposed. A second opinion is also possible.

Over time, the breasts change: pregnancy, weight loss, menopause, skin ageing. An additional fat transfer session can then restore volume to the upper breast or correct an asymmetry that has appeared. It is possible as long as fat remains available, possibly in different areas from previous ones. Tissues already grafted generally accept a new graft well.

Fat transfer does not exempt you from breast cancer screening, which continues according to your age and history. Always tell the radiologist about the procedure, with its date. Images linked to grafted fat, such as oil cysts and benign calcifications, have a typical appearance; comparison with previous examinations allows them to be monitored. If in doubt, an ultrasound, MRI or biopsy allows a conclusion to be reached.

• The operative report, with the donor areas and the volumes injected.
• The imaging performed before and after the procedure.
• The dates of the different sessions.
• The quote, invoices and, in reconstruction, the coverage decision.

These documents are valuable for screening, a possible additional session or another breast procedure.

Before fat transfer, a mammogram and ultrasound are performed according to age and history, to check for any lesion and have reference examinations. After the procedure, grafted fat can leave small images: oil cysts, rounded calcifications, areas of fat necrosis. They are benign and have a characteristic appearance that experienced radiologists recognise, especially if informed of the procedure.

Reference imaging six months to a year after fat transfer is often advised for women of screening age, to compare future examinations. If an image is in doubt, an additional ultrasound, MRI or biopsy allows a decision to be made.

After fat transfer, it is advisable to have a reference mammogram or ultrasound, often six months to a year after the last session, for women of screening age. This examination shows the appearance of the grafted fat once stabilised, with any small cysts or calcifications. At subsequent examinations, the radiologist can compare and more easily spot any new abnormality. Keep these images and bring them to check-ups.

Part of the injected fat that did not survive can turn into an oil cyst, a small pocket of liquid fat, or fat necrosis, a small firm lump. These formations, more common when large amounts are injected at once, are benign. They may be palpable, sometimes tender, and worrying. Ultrasound generally identifies them. A bothersome cyst can be aspirated; a firm area often decreases over time.

The risk of infection after fat transfer is low. It is reduced by careful disinfection, sterile conditions and sometimes an antibiotic at the time of the procedure. After the procedure, keep the small incisions clean and dry, change the dressings as instructed, and avoid baths and swimming pools until they have closed. Spreading redness, warmth, increasing pain or fever require prompt medical attention.

Fat embolism, the passage of fat into the bloodstream, is an exceptional but serious complication, described mainly with large injections in certain regions, notably the buttocks. For the breasts, it remains extremely rare. Surgeons prevent it by using blunt-tipped cannulas, injecting slowly, in small amounts, while moving, and avoiding dangerous areas. Sudden breathlessness, chest pain or confusion after the procedure require a call to 144.

Uneven distribution of the fat or uneven resorption can create small surface irregularities on the breasts, such as a firmer area or a slight hollow. They are rare with an injection technique using thin layers. They often soften over time and can be corrected at a second session or with a small additional procedure.

• Pain that increases instead of decreasing.
• Spreading redness, warmth, fever.
• Discharge from an incision.
• Sudden swelling of a breast or a donor area.
• Breathlessness, chest pain, difficulty breathing.
• A warm, painful, swollen calf.

In the event of breathlessness or chest pain, call 144. For other signs, contact the team without delay.

As with any liposuction, there is a risk of a blood clot in the leg veins, especially if the donor areas are extensive, if the procedure is long, or with the pill, smoking, being overweight or a history of clots. Prevention relies on getting up early, walking regularly, the compression garment, sometimes compression stockings and anticoagulant injections. Mention your history at the anaesthesia consultation.

Venous thrombosis shows as a warm, swollen, painful calf, sometimes red, often on one side only. It can be complicated by a pulmonary embolism, which causes sudden breathlessness, chest pain or palpitations. These signs, which are rare, require an urgent consultation or a call to 144. Getting up early, walking and the compression garment reduce this risk.

• The consultation: wish for one size more, fat on the abdomen and hips; two sessions planned.
• Session 1: two hours, home in the evening, compression garment.
• First week: painful, bruised hips, swollen breasts.
• Six weeks: bruising gone, breasts have deflated slightly.
• Six months: a gain of half a size to one size; second session.
• One year: fuller breasts, natural feel, slimmer waist.

• Two years after breast-conserving treatment and radiotherapy, a hollow and firm skin on one breast.
• Oncology team's opinion: fat transfer possible.
• Request for coverage approved.
• Session 1: partial filling, skin already softer after three months.
• Session 2: symmetry clearly improved.
• Follow-up: mammograms interpreted by an informed radiologist, normal results.

• Implants placed fifteen years earlier, wish to have them removed.
• Procedure: removal of the implants and capsules, vertical lift, fat transfer to the upper breasts.
• Two weeks: back at work, smaller but shapely breasts.
• Six months: partial resorption, a small additional session being considered.
• One year: happy with natural breasts, without implants.

Successful fat transfer gives fuller breasts with a natural feel and a slimmer figure in the donor areas. It does not radically change volume in one session, does not lift sagging breasts, and its result depends partly on fat survival, which varies from one person to another. The most satisfied patients are those who sought a subtle change, accepted the idea of two sessions and waited six months to judge.

Many women who choose fat transfer want a discreet change that suits them, without the feeling of having an implant in their breasts. They appreciate being able to say that it is their own fat and regaining a more harmonious figure, with slightly fuller breasts and a slimmer waist or hips. This double benefit often contributes to a better self-image.

Patients often describe the surprise of the first few weeks: breasts larger than expected, then a worrying decrease, before the volume stabilises. Many appreciate the natural feel and slimmer figure, and stress that the donor areas were more uncomfortable than the breasts. Disappointments mainly concern a gain considered too modest after a single session, which underlines the importance of clear information at the outset.

Breast fat transfer is performed by plastic surgeons in most cantons, in practices, clinics and hospitals. In French-speaking Switzerland, Geneva and Lausanne offer the widest choice, followed by the Riviera, Fribourg, Neuchâtel and Sion. In German-speaking Switzerland, Zurich, Basel, Bern, Lucerne and St. Gallen concentrate the provision. In Ticino, Lugano and Bellinzona offer the procedure, with consultations in Italian.

For reconstructive fat transfer, the breast centres of university and cantonal hospitals, which bring together oncologists, radiologists and plastic surgeons, are the preferred points of contact.

These differences concern cosmetic fat transfer. In reconstruction, the procedure is covered by basic insurance. Details are on our page on breast fat transfer prices.

For cosmetic fat transfer, a consultation appointment is generally obtained within a few weeks, and the procedure scheduled a few weeks later. For reconstructive fat transfer, waiting times depend on the oncology schedule and hospital waiting lists. Comparing several facilities, in your canton or a neighbouring canton, can shorten the wait.

Cosmetic fat transfer is usually performed in a private clinic or a practice with an authorised operating theatre, as day surgery. Reconstructive fat transfer is often performed in hospital or in a clinic linked to a breast centre, in coordination with the oncology team. In all cases, check the facility's authorisation, the presence of an anaesthetist and how follow-up is organised.

These indices are consistent with those on our breast augmentation and breast surgery guide pages.

Cosmetic fat transfer, intended to increase volume or harmonise the breasts without medical reason, is at the patient's expense. However, it is covered by basic insurance when it is part of reconstruction after breast cancer, symmetrisation, or correction of a congenital malformation such as Poland syndrome or marked tuberous breasts. A prior cost approval request is then necessary. Wait for the insurer's written reply before setting the date.

When fat transfer is part of reconstruction after cancer, symmetrisation or correction of a malformation, the surgeon sends a cost approval request to your health insurer. It includes a report describing the situation, the indication, the number of planned sessions and photos. In reconstruction after cancer, approval is generally given without difficulty. For malformations, such as tuberous breasts, the decision depends on the extent of the deformity and associated problems.

Wait for the written reply before setting the date. If fat transfer is covered, you pay your deductible (franchise) and co-payment (quote-part), as for any basic insurance treatment.

Marked tuberous breasts are a developmental malformation, which may be the subject of a request for coverage, particularly when they cause significant asymmetry or documented psychological distress. The decision rests with the insurer and its medical adviser, case by case. The surgeon prepares the file with photos and a description of the deformity. Mild forms are generally considered cosmetic.

For fat transfer that is covered, check the conditions of your insurance model: with a family doctor, health network or telemedicine model, going through your primary care doctor first is often compulsory before consulting the surgeon. For cosmetic fat transfer, these rules do not apply, as the procedure is at your expense.

• Specialist title in plastic, reconstructive and aesthetic surgery, verifiable on MedReg.
• Regular experience of breast fat transfer, cosmetic or reconstructive.
• Honest explanation of resorption and the number of sessions.
• Ability to propose an implant or hybrid technique if fat transfer alone is not enough.
• Photos of results at six months or one year.
• Collaboration with radiologists used to breasts after fat transfer.

Be wary of promises of large gains in a single session, or of techniques presented as revolutionary without solid evidence.

Patients often cite the same reassuring elements: a surgeon who took time to explain resorption and the number of sessions, who examined the donor areas, who showed real long-term results and who presented the alternatives honestly. A clear quote, including the conditions for a second session, and a number you can reach after the procedure complete this trust.

Fat transfer seems simple: harvest, prepare, reinject. In reality, each step requires experience: harvesting without damaging the cells or creating irregularities, preparing the fat with as little handling as possible, injecting it in thin layers, at the right depth, in the right amount, while respecting the safety rules. Results vary greatly with the surgeon's experience. Ask how many breast fat transfers they perform and to see long-term results.

A second opinion is useful if you are hesitating between fat transfer, an implant and a hybrid technique, if you are promised a very large volume gain, or if you are offered expensive enrichment techniques. Compare the explanations about resorption, donor areas and the number of sessions. A cautious proposal that is honest about the limits is often the most reliable.

If two surgeons make different proposals, for example one suggesting fat transfer in two sessions and the other an implant, compare their explanations: estimate of the available fat, likely gain, number of sessions, resorption, recovery, long-term follow-up and total cost. A proposal that is honest about the limits of fat transfer is a sign of seriousness. Do not hesitate to ask each of them why they are not proposing the other's option.

Before the procedure, you receive written information about the technique, donor areas, resorption, the likely number of sessions, the risks, including cysts and images on mammograms, and recovery. Read it at home and ask your questions. You can withdraw until the last moment.

As fat transfer often requires two sessions for a gain of one to two sizes, it is useful to think in terms of the total budget. A second session is sometimes offered at a reduced rate, but it again includes anaesthesia and clinic costs. Compared with implant augmentation, the initial cost may be similar or higher; on the other hand, fat transfer does not require regular check-ups or future exchanges linked to an implant.

To compare the cost of fat transfer with that of implant augmentation, you need to think about the whole journey: the number of planned sessions, anaesthesia and clinic costs at each session, compression garments, imaging. On the implant side, you need to add regular check-ups and the likelihood of one or more exchanges during a lifetime. Over twenty years, the differences often narrow. The choice remains above all a question of the desired result and personal preference.

The price of each session is supplemented by the compression garment, sometimes soft bras, medicines, imaging before and after, days off work and travel. If two sessions are needed, these costs are repeated. In return, fat transfer does not involve long-term costs linked to implants, such as regular check-ups or implant exchanges.

Each fat transfer session is a procedure in its own right: anaesthesia, operating theatre, harvesting, preparation, injection, monitoring. That is why a second session is not free, even if some surgeons offer a reduced rate on their fees. Budgeting for two sessions from the outset avoids unpleasant surprises and allows an honest comparison with implant augmentation.

A deposit is often requested when booking the date. Ask about the conditions for postponement in the event of illness, infection or very heavy periods, and the cancellation conditions. Also ask in writing for the financial conditions of a possible second session.

Autumn and winter are often preferred: the compression garment is easier to wear under covering clothes, and bruising on the donor areas goes unnoticed. Avoid periods of travel, swimming or important events in the following weeks. If two sessions are planned, schedule them three to six months apart, taking your personal calendar into account.

Understanding resorption, the number of sessions and imaging follow-up requires clear explanations. In French-speaking Switzerland, everything takes place in French. In the major German-speaking cities, many plastic surgeons see patients in French or English; mention this when booking. In Ticino, consultations are in Italian. Ask for a written summary of the treatment plan.

For residents of outlying regions, the consultation and procedure often take place in a neighbouring town. As two sessions are common, distance matters more than for a single procedure. Group appointments together, ask for a first opinion based on photos, and see whether some check-ups can be done remotely or with your GP. Imaging follow-up can be done near home, with an informed radiologist.

• It does not guarantee a precise volume, because of resorption.
• It does not replace breast cancer screening.
• It does not correct capsular contracture around an implant.
• It is not always suitable for very slim women.

• Fat transfer: transfer of the patient's own fat.
• Lipomodelling: another name for fat transfer.
• Autologous fat: fat coming from the patient themselves.
• Resorption: the part of the grafted fat that disappears.
• Oil cyst: a benign pocket of liquefied fat.
• Fat necrosis: a small, benign firm lump.
• External expansion: a device that stretches the skin before injection.
• Hybrid augmentation: implant and fat combined.
• Decanting: separation of the fat by gravity.

• Fat transfer uses your own fat to shape the breasts.
• The result is natural, and the figure is slimmed.
• The gain is moderate, often one size per session.
• Some of the fat is resorbed; two sessions are common.
• Imaging remains possible with an informed radiologist.
• It is covered in reconstruction, and at the patient's expense when cosmetic.

Choosing fat transfer, an implant, a hybrid technique or not changing anything is a personal decision. Fat transfer is attractive for its naturalness and the absence of an implant, at the cost of a more modest gain and a degree of uncertainty linked to resorption. Take time to understand these trade-offs, consult an experienced surgeon and decide at your own pace. An information consultation commits you to nothing.

Before deciding, take time to picture yourself: what volume do you really want, are you prepared to accept two sessions, do you have enough fat, and do you prefer to avoid an implant? If the answers point you towards fat transfer, choose an experienced surgeon who speaks frankly about its limits. If they point you towards another option, fat transfer can always complement an implant or a lift later, to refine the contour and cleavage naturally and lastingly, without a new implant.

Breast fat transfer turns a little fat you would like to get rid of into natural volume for the breasts. When well indicated, with realistic expectations, it gives lasting results with a natural feel and no implant to monitor. Its success depends on good injection technique, a stable weight, stopping smoking and the patience needed to let the fat integrate.

Successful breast fat transfer can be recognised by a few signs: fuller, more harmonious breasts with a natural feel and no visible scars; slimmer, even donor areas; imaging correctly interpreted by an informed radiologist; and a patient who has understood and accepted the pace of the sessions. Many women describe a result that suits them, which they quickly forget in daily life, while enjoying the figure they have regained.

If this description matches what you are looking for, an information consultation is the next step. Our team can help you find an experienced plastic surgeon near you, in your language, and obtain a first opinion based on photos, without obligation. This first exchange often lets you know within a few days whether your plans are realistic, how many sessions would be needed and which areas could be harvested.

Breast fat transfer offers a natural way to shape the breasts, correct asymmetry or improve a reconstruction, without an implant and with a slimmer figure as a bonus. Its limits — moderate gain and partial resorption — must be well understood. When well indicated and performed by an experienced surgeon, it gives lasting, highly appreciated results.

Answers to the most frequent questions about breast fat transfer in Switzerland.

Understanding breast fat transfer

What is breast fat transfer? It is a transfer of your own fat to the breasts. The surgeon suctions fat with fine cannulas from an area that has some, purifies it, then reinjects it in very small amounts into the breasts, at different depths. The fat that survives becomes permanently integrated into the breast tissues.

What is breast fat transfer used for? It is used to moderately increase volume, correct asymmetry, fill the upper breast or cleavage, hide the edges of an implant, correct tuberous breasts or a deformity, and reconstruct or improve a breast after cancer.

What volume gain can I expect? On average, about one cup size per session, sometimes a little more in women with supple skin and plenty of fat. For a larger gain, several sessions are needed, or a combination with an implant.

Does all the injected fat stay? No. Some of the injected fat does not survive and is resorbed during the first weeks and months, often around a third to a half depending on studies, techniques and patients. The fat remaining after three to six months is considered permanent.

Is the result permanent? The fat that has survived after six months behaves like fat elsewhere in the body: it stays in place, but varies with weight. Weight gain slightly increases breast volume, weight loss reduces it. The result requires no particular follow-up, unlike implants.

Is a lot of fat needed for fat transfer? You need a sufficient amount of fat to harvest, generally several hundred millilitres to treat both breasts, as some is eliminated during purification and some is resorbed. Very slim women sometimes do not have enough fat; the surgeon assesses this at the examination.

Where is the fat harvested from? Usually the abdomen, hips, inner or outer thighs, knees or flanks. The surgeon chooses areas where fat is available and where slimming is desired, taking your preferences into account.

Is the donor area slimmed? Yes, harvesting is a gentle liposuction that slims the treated area. It is an appreciated benefit. However, the main aim remains to harvest good-quality fat, and the harvesting is less aggressive than purely cosmetic liposuction.

Does it feel natural? Yes, this is one of the main advantages: grafted fat gives a soft breast with a natural feel, no palpable edges and no sensation of implanted material. The breast also moves naturally.

Does fat transfer lift the breasts? No. It adds volume, which can slightly improve slightly emptied breasts, but it does not lift a descended areola or remove excess skin. For sagging breasts, a lift is combined.

Is fat transfer suitable for small breasts? Yes, but the gain per session is limited by skin elasticity: very firm skin and small breasts accept less fat at once. Several sessions, or preparation of the skin by external expansion at some centres, may be offered.

Can I choose my final size? Not as precisely as with an implant, as resorption varies from one person to another. The surgeon gives you an estimate and can adjust with a second session. If a precise volume is important to you, an implant or a hybrid technique may be more suitable.

Does fat transfer leave scars? Only small incisions of a few millimetres, on the donor areas and around the breasts, often in the fold or at the edge of the areola. They become very discreet within a few months.

Is fat transfer painful? The donor area is the most painful, as after liposuction: tenderness, bruising and aching for one to two weeks. The breasts are slightly tight and tender. Simple painkillers are generally enough.

How long does the procedure take? One to three hours depending on the amount of fat harvested and injected. It is generally performed as day surgery under general anaesthesia, sometimes under local anaesthesia with sedation for small volumes.

Can I breastfeed after fat transfer? Yes. Fat transfer does not damage the gland or the ducts. Breastfeeding remains possible, and the grafted fat does not pass into the milk.

Does fat transfer change sensation? Rarely. The injections are made with fine cannulas that do not damage the nerves of the areola. A slight temporary change in sensation may be felt in the first few weeks.

Is fat transfer recent? No. Fat transfer has been practised for more than a century, but its modern techniques, with fine cannulas and injections in small amounts, have developed since the 1990s. It is now a recognised technique in reconstructive and cosmetic breast surgery.

What is hybrid augmentation? It is the combination of an implant and fat transfer. The implant provides the main volume, the fat softens the contours and covers the edges of the implant. See our page on breast augmentation.

Do stem cells play a role? Fat contains cells with regenerative properties, sometimes called adipose-derived stem cells, which may promote graft survival and improve skin quality. Some techniques aim to enrich them. Their real value is still being studied; be wary of commercial promises.

Indications

Who is fat transfer alone suitable for? For women who want a moderate, natural gain, have fat to harvest, prefer to avoid an implant and its follow-up, and accept the possibility of two sessions.

Can fat transfer correct asymmetry? Yes, it is an excellent indication: more fat is injected on the smaller side. Several sessions may be needed for significant asymmetry. It can also complement an implant or a reduction on the other side.

Can fat transfer correct tuberous breasts? Yes, it is often used to fill the narrow base and correct the shape of tuberous breasts, sometimes combined with release of the gland, lowering of the fold or areola reduction. Several sessions are often needed.

Does fat transfer help after implant removal? Yes. After implants are removed, the breasts often look empty. Fat transfer, sometimes combined with a lift, restores volume and a natural shape without a new implant. See our page on implant removal with a lift.

Does fat transfer correct the visible edges of an implant? Yes. In slim women, the folds or edges of an implant can be seen or felt. A layer of fat injected between the skin and the implant hides them. It is a common indication for fat transfer.

Is fat transfer used in reconstruction? Yes, widely. It improves the shape and softness of a breast reconstructed with an implant or flap, fills hollows after breast-conserving treatment, improves skin damaged by radiotherapy, and can sometimes reconstruct a breast over several sessions. It is then covered by insurance.

Can fat transfer entirely reconstruct a breast? In some selected cases, a breast can be reconstructed using fat transfer alone, over several sessions, sometimes after prior expansion of the skin. This takes time and enough fat. Most often, fat transfer complements another technique.

Does fat transfer improve irradiated skin? Grafted fat seems to improve the suppleness, quality and blood supply of tissues damaged by radiotherapy, which sometimes makes later reconstruction easier. It is a recognised indication in reconstruction.

Is fat transfer suitable for Poland syndrome? Yes, it is used to correct the absence of the pectoral muscle and breast asymmetry, often over several sessions, alone or combined with an implant. These situations are covered as a congenital malformation.

Does fat transfer correct a sunken chest? It can improve the appearance of pectus excavatum or hollow cleavage by filling the depression, often over several sessions. Severe forms sometimes call for other treatments.

Is fat transfer suitable for trans women? Yes, it can complement the breast development achieved with hormone therapy or soften the contours of an implant. The gain remains moderate per session.

Is fat transfer suitable for very slim women? Often less so, as the available fat is limited. The surgeon assesses the amount that can be harvested. A small amount may nevertheless be enough to hide the edges of an implant or correct a small defect.

Can fat transfer be done after a breast reduction? Yes, if the breasts look empty at the top or have a small hollow. It is a useful touch-up, performed once the result has stabilised.

Does fat transfer improve the cleavage? Yes, it can fill the area between the breasts and the upper chest for a more harmonious cleavage, within the limits of anatomy. It cannot bring the breasts closer together beyond the position of the muscles.

Is fat transfer suitable after pregnancy? Yes, it can restore a little volume to breasts emptied after breastfeeding, provided the areola has stayed well positioned. If the breasts are sagging, a lift is combined. Wait at least six months after weaning.

Is fat transfer suitable after fifty? Yes, age is not an obstacle. The skin is often more supple, which makes injection easier, but tissue quality and fattier breasts change the result. A recent mammogram is essential.

Is fat transfer suitable for sportswomen? Yes, it leaves no implant that could move when the pectorals contract and gives natural volume. Sport resumes quickly, avoiding compression of the breasts in the first month.

Can fat transfer be done if I have implants? Yes, by injecting the fat between the skin and the implant, carefully so as not to touch it. This is often done to hide the edges of an implant or improve the cleavage.

Does fat transfer correct capsular contracture? It does not treat the contracture itself, which generally requires removal of the capsule and implant exchange. It can, however, improve coverage and contour after correction.

Can fat transfer be done during abdominal liposuction? Yes, in fact it is often done this way: fat suctioned from the abdomen or hips is reused for the breasts, combining two benefits in one procedure.

Can injected fat harden? Sometimes, part of the fat that did not survive forms small firm areas or cysts. They are benign. An injection technique using small amounts reduces this risk.

Is the result symmetrical? Resorption may differ slightly from one breast to the other. A small asymmetry can be corrected at a second session.

Can fat transfer be done under local anaesthesia? For small amounts, for example a touch-up or correction of a hollow, local anaesthesia with sedation is possible. For augmentation of both breasts, general anaesthesia is more comfortable.

Is a blood test needed? Depending on age, health and the extent of the procedure, a blood test and an anaesthesia consultation are arranged before the procedure.

Does fat transfer improve skin quality? In some situations, particularly on irradiated or scarred skin, grafted fat seems to improve the suppleness and appearance of the skin. In cosmetic surgery, this effect is more subtle.

Can I get a tattoo after fat transfer? Yes, once healing is complete and the result has stabilised, after a few months. Avoid tattooing directly over an area where cysts have been identified, and tell the tattoo artist.

Do the breasts change with age after fat transfer? Yes, like natural breasts: the grafted fat changes with weight, menopause and skin ageing. The result ages naturally, without implant-related complications.

Can breast fat transfer be combined with buttock augmentation? Yes, the harvested fat can be shared between the breasts and buttocks during the same procedure, if the amount available allows. The surgeon assesses whether this is reasonable.

What if the volume obtained is insufficient? A second session can be performed three to six months later, if fat remains available. Otherwise, a hybrid technique with a small implant can complement the result.

Technique and sessions

How is the fat harvested? Through small incisions, the surgeon injects a solution that numbs the area and limits bleeding, then suctions the fat with fine cannulas at low pressure to preserve the cells. It is a gentle liposuction.

How is the fat prepared? It is separated from fluids, blood and oil by decanting, filtration or light centrifugation, depending on the surgeon's practice. The aim is to obtain concentrated, good-quality fat with as little handling as possible.

How is the fat injected? With fine cannulas, in multiple passes, depositing tiny amounts at different depths and in different directions. Each small deposit must be surrounded by vascularised tissue to survive. Injecting too much in one place encourages cysts and resorption.

How much fat is injected per breast? Often between one hundred and three hundred millilitres per breast per session, sometimes more, depending on the space available, the suppleness of the skin and the amount of fat harvested. The surgeon does not force it, to preserve fat survival.

How many sessions are needed? One session for a slight correction, two or three for a larger volume gain or a reconstruction. Sessions are spaced three to six months apart, until the grafted fat has stabilised.

Should the skin be prepared beforehand? At some centres, an external vacuum expansion system, worn several hours a day for a few weeks before the procedure, enlarges the space and promotes fat survival. It requires great diligence and is not used everywhere.

Can fat transfer be combined with an implant? Yes, this is the hybrid technique. It combines a clear volume and a natural contour, particularly in slim women.

Can fat transfer be combined with a lift? Yes, it can fill the upper breast during a lift or correct a hollow afterwards. It is often performed at the same time or a few months later.

Can fat transfer be combined with cosmetic liposuction? Yes, liposuction of the donor areas can be more extensive to slim the figure. See our page on breast fat transfer with liposuction.

How does the surgeon avoid irregularities? By injecting small amounts distributed evenly, avoiding depositing too much in the gland itself, and checking the result by palpation and in a sitting position.

Is a compression garment needed? Yes, on the donor areas, for a few weeks, to limit swelling and help the skin retract. On the breasts, a soft bra without compression is preferred, so as not to crush the grafted fat.

Recovery

How long does recovery take? The breasts recover quickly; it is mainly the donor areas that are tender for one to two weeks. A return to office work is often possible after three to seven days, sport after three to four weeks.

Should I avoid compressing the breasts? Yes, in the first few weeks, so as not to crush the grafted fat and compromise its survival. Avoid tight bras, underwiring and sleeping on your front for about four weeks.

When is the final result visible? The volume decreases during the first few weeks as swelling and some of the fat are resorbed. The result stabilises at around three to six months. Any second session is decided at that point.

Do I need to keep a stable weight? Yes. Avoid losing weight in the months after the procedure, as weight loss reduces the volume of grafted fat. A stable weight preserves the result.

Can I do sport after fat transfer? Walking from the first few days, gentle sport after two weeks, intense sport after three to four weeks, depending on how tender the donor areas are. Avoid knocks and compression of the breasts in the first month.

Is bruising significant? It is common on the donor areas, sometimes extensive, and disappears within two to three weeks. On the breasts, it is generally more limited.

When can I return to work? For office work, often after three to seven days. For a physical job, after two to three weeks, depending on the donor areas.

Is cold recommended? On the donor areas, a little cold through a cloth can bring relief. On the breasts, it is generally avoided, so as not to reduce the circulation needed for fat survival. Follow the surgeon's instructions.

Can I smoke after fat transfer? No, smoking reduces circulation and the survival of the grafted fat, and increases complications. You must stop several weeks before and after.

Should I massage my breasts? Not in the first few weeks, so as not to displace the fat. Massage of the donor areas may be advised after a few days to soften the tissues.

Safety and imaging

Is fat transfer safe? It is a generally safe procedure with a low complication rate. The most common side effects are bruising, more resorption than expected, small oil cysts or firm areas. Serious complications are rare.

Does fat transfer increase the risk of breast cancer? Available studies have not shown an increased risk of breast cancer after cosmetic fat transfer. In reconstruction after cancer, the data are reassuring, but careful oncological follow-up is maintained. Breast imaging is performed before the procedure.

Does fat transfer interfere with mammography? It can create small images, such as oil cysts or calcifications, which must be distinguished from suspicious lesions. Experienced radiologists recognise them, especially if informed of the fat transfer. It is advisable to have reference imaging a few months afterwards.

What is an oil cyst? It is a small pocket filled with liquefied fat, formed when part of the grafted fat has not survived. It is benign, often painless and may be palpable. It can be seen on ultrasound and can be aspirated if bothersome.

What is fat necrosis? It is an area of fat that lacked blood supply and has turned into a small firm lump. It is benign but can be worrying. Ultrasound allows it to be recognised; if in doubt, aspiration or a biopsy confirms its nature.

What are the other risks? Infection, which is rare; irregularities on the donor areas; asymmetric resorption between the two breasts; and, very rarely, fat embolism, a serious complication linked to fat being injected into a blood vessel, which current techniques with blunt-tipped cannulas make exceptional.

Is a mammogram needed before fat transfer? Yes, depending on age and history, a mammogram and ultrasound are performed before the procedure, to check for any lesion and serve as a reference.

Is fat transfer possible with a family history of breast cancer? It is possible, but must be discussed with the surgeon and, if necessary, the gynaecologist or oncologist. Screening adapted to the family risk must be up to date, and imaging follow-up continues after the procedure.

Should I tell the radiologist? Yes, always. Give the date and nature of the procedure at every breast imaging examination. This avoids unnecessary further tests and makes interpretation easier.

What should I do if a lump appears? See your doctor. A lump after fat transfer is most often an oil cyst or fat necrosis, both benign, but any new lump must be examined by ultrasound and, if necessary, biopsied.

Practical questions

How should I prepare for the consultation? Think about the volume you want and the areas where you have fat that you would like slimmed, and bring your recent breast examinations and the list of your treatments. Mention any family history of breast cancer.

Should I gain weight beforehand? It is generally not advisable to gain weight specifically for the procedure, as fat gained and then lost will make the result vary. The surgeon assesses the fat available at your usual weight.

Should certain medicines be stopped? Those that encourage bleeding, such as aspirin or certain supplements, are often stopped a few days beforehand, on medical advice. Anticoagulants must never be stopped without the prescriber's agreement.

What should I prepare at home? Soft bras without underwiring, compression garments for the donor areas, loose clothing, pillows to sleep on your back, and help for the first few days.

Can I sleep on my front? Not for about four weeks, so as not to compress the breasts. Sleep on your back or on your side depending on the donor areas.

When can I wear an underwired bra? After about four to six weeks, once the grafted fat has stabilised, with the surgeon's agreement.

Can I fly? Yes, after one to two weeks for a short journey; for a long trip, ask the surgeon's advice because of the risk of thrombosis. Wear your compression garments and walk regularly.

When can I go swimming? Once the small incisions have closed, generally after one to two weeks. Avoid long hot baths and saunas for a few weeks.

Can the fat migrate? No, the grafted fat stays where it was injected and develops its blood supply there. It can only be partially resorbed.

Can fat transfer be repeated later? Yes, an additional session is possible if the desired volume has not been reached, or years later, provided fat is still available.

Price, insurance and locations in Switzerland

How much does breast fat transfer cost? The price depends on the number of donor areas, the amount of fat, the duration and the number of sessions. We express it as relative indices on our price page. Remember to allow for a possible second session in your budget.

Is fat transfer reimbursed? Cosmetic fat transfer is at the patient's expense. In reconstruction after cancer, for symmetrisation, and for certain malformations such as Poland syndrome or marked tuberous breasts, it may be covered by basic insurance after a cost approval request.

Is the second session included? Rarely. Each session is generally billed separately, sometimes at a reduced rate. Ask clearly before committing.

What should the quote specify? The number of donor areas, the planned duration, the anaesthesia, the clinic, compression garments, check-ups included and the conditions for a second session.

Where can I have breast fat transfer in Switzerland? Plastic surgeons perform it in most cities: Geneva, Lausanne, Bern, Basel, Zurich, Lucerne, St. Gallen, Lugano and many medium-sized towns. Hospital breast reconstruction centres also use it widely.

How do I choose my surgeon? Choose a surgeon holding the specialist title in plastic, reconstructive and aesthetic surgery, who regularly performs breast fat transfer, explains resorption and the number of sessions honestly, and shows you results at six months or one year.

Can I consult in French in German-speaking Switzerland? In the major cities, many surgeons speak French or English. Mention this when booking.

Is a second opinion needed? It is useful if you are hesitating between fat transfer, an implant or a hybrid technique, or if you are promised a large volume gain in a single session. Compare the explanations and the results shown.

How much time should I allow in total? For two sessions spaced three to six months apart, allow six months to a year between the first consultation and the final result.
