Breast augmentation with own fat — no implant, no scars on the breast, no foreign body in the body. Fat is harvested from the abdomen, flanks or thighs and gently injected into the breast. Natural feel, natural result. For women who desire more fullness without a silicone implant.

A breast from yourself.
No foreign substance. No feeling of something hard.
Natural — in every movement.
— Your body, completed.
Three phases: WAL harvest from donor zone · sterile processing · micro-bolus injection into the breast.
Four medically decisive facts — that you should know before deciding.
Injected adipocytes have no own blood circulation in the first 48 hours. They survive by diffusion from surrounding tissue. Diffusion only works over maximum 2 mm distance.
Therefore: Dr. Fetai injects in thousands of micro-depots (max 0.1 ml per bolus) — never as a single large volume. So every microliter is within diffusion reach. Result: 70–80 % engraftment rate instead of 30–40 % with "block injection".
Aspirated fat tissue contains, besides mature adipocytes, the SVF (Stromal Vascular Fraction) — adipogenic stem cells, endothelial precursors, growth factors. This fraction is the key to engraftment.
With the WAL technique SVF is maximally preserved (98 % vitality vs. 60–70 % with classical lipo). Studies show: higher SVF fractions correlate with better engraftment rate and even with local skin tightening in the recipient zone.
International studies (ASAPS, ASPS consensus 2009 + updates) have shown: autologous fat transfer into the breast is oncologically safe and does not impair either mammography or MRI screening when performed correctly.
Important: micro-bolus technique avoids oil cysts/calcifications that could disturb mammography images. Dr. Fetai documents current mammography/ultrasound as baseline before every OP — and recommends control imaging 6 months post-OP.
Per breast side maximum 200–300 ml can be injected in one session — more would exceed diffusion range and risk necrosis. 200 ml correspond roughly to one cup size.
For 2 cup-sizes Dr. Fetai recommends a second session after 6 months (when the first is fully engrafted and vascularised). This second session even has better engraftment rates because the recipient tissue is then better perfused.
Final vitals, OP gown, compression stockings. Dr. Fetai marks both zones with violet pen: donor zone (usually abdomen + flanks + inner thighs — to be contoured today as well) and recipient zone breast with the anatomical vectors of injection.
Klein solution infiltrates the donor zone, then Body-Jet works at 0.5–2 bar. 500–700 ml of highly vital fat is harvested — your abdomen/hips are tightened simultaneously (a deliberate double effect). You feel nothing, only the soft pumping.
The harvested fat is washed in a closed system, separated from tumescence, blood and cell debris. What remains: pure adipocytes + SVF stem cells — in sterile 10-ml syringes ready for injection.
With ultra-thin blunt cannulas (2 mm) fat is injected in 3 layers: subglandular, intermuscular, retroglandular. Never into the glandular tissue itself. Per breast about 200 ml, in thousands of 0.1-ml micro-bolus depots — Dr. Fetai counts every syringe.
You stand — Dr. Fetai compares standing, corrects micro-asymmetries. Special bra (no underwire), garment below. 4 weeks no pressure bra, 4 weeks no sport. Day 2 already short walks. After 8 weeks you see 70 % of the result — after 6 months 100 %, then stable for decades.
Five assumptions we meet daily — and what really stands.
"Autologous fat is completely broken down again."
With correct micro-bolus technique 70–80 % engraft permanently. The rest breaks down in the first half year — that is predictable and calculated with slight overfill in planning.
"Autologous fat breast is more dangerous than implants."
The opposite: no BIA-ALCL risk, no capsular fibrosis, no rupture, no 10-year replacement OP. The only safe alternative for patients with implant concerns.
"With this I can no longer do mammography."
Mammography and MRI remain fully possible. Trained radiologists clearly distinguish autologous-fat changes from suspicious findings. Baseline imaging before and 6 months post-OP recommended.
"Autologous fat only works on thin breasts — mine is already too saggy."
Autologous fat is volume correction, not lifting. With strongly relaxed tissue a mastopexy must be combined — Dr. Fetai decides honestly in the consultation.
"I don't have enough body fat."
Even with BMI 20 there are usually 500–800 ml donor volume (abdomen + flanks + inner thighs + knees). Very slim patients may need a brief weight phase or two smaller sessions.
Five questions we ask in the consultation anyway — answered honestly to yourself is a good filter.
You need min. 500 ml donor volume for a visibly fuller breast — with BMI > 21 almost always possible. Abdomen, flanks, inner thighs are contoured in the same OP — double effect.
Per session +1 cup-size is realistic (200 ml engraftment per side). Anyone wanting 2+ cups needs 2 sessions with 6 months pause — we plan transparently.
Smoking dramatically reduces engraftment rate (vasoconstriction → poor diffusion). 4 weeks before & after OP no cigarette. Honest condition — we gladly postpone.
Before every breast-autologous-fat OP we require current breast imaging (max. 12 months old) — as baseline and for risk clarification. Mandatory.
First 3 months 20–30 % of volume breaks down again — this is normal and predictable. Final result after 6 months. Anyone seeking "instant maximum" should speak honestly with Dr. Fetai.
Three medical-neurobiological points patients often report post-OP — and the physiology behind them.
Implants have no own sensors — patients often report a "foreign body feeling" that can last years. Autologous-fat breast integrates into the somatosensory map: the brain registers it as own tissue within 6–8 weeks.
Somatosensory integration · PenfieldTransplanted adipocytes retain their endocrine activity — they produce leptin, adiponectin and respond to oestrogen cycles. That means: the breast behaves biologically like a natural breast, not like a static implant.
Adipocyte endocrinologyPatients report in over 70 % of cases improved skin quality at the décolleté — tighter, thinner skin, fewer stretch marks. The SVF stem cell fraction acts regeneratively also on the surrounding recipient tissue.
Coleman · SVF regeneration"Patients weighing implant vs. autologous fat I always ask: What do you want in 20 years? Implants need maintenance. Autologous fat — once engrafted — is yours. It ages with you, breathes with you, feels like what it is: you. That is the answer I would give myself if I were the patient."
Per session typically +1 cup size (e.g. A→B or B→C). For more, a second session after 6 months is needed. The second session even engrafts better because recipient tissue is then optimally perfused.
What is engrafted after 6 months (70–80 %) stays for decades — like your own tissue. It ages with you, fluctuates minimally with weight changes. No replacement OP, no 10-year limit like with implants.
Yes — autologous fat is injected exclusively subcutaneous and intermuscular, never into glandular tissue. Milk ducts remain untouched. Breastfeeding is fully possible after healing.
Dr. Fetai is a private physician only. The OP is calculated as an individual private service under GOÄ. Realistic range: €7,500–12,000 per session (including donor contouring as bonus). Binding written cost estimate in the free first consultation.
Office work after 3–5 days, physical work after 2 weeks, sport from week 4 (chest sport from week 6). 4 weeks no tight bra (no pressure on freshly transplanted micro-bolus depots). Special bra (sport type, no underwire) for 4–6 weeks.
Typical OP risks (haematoma, infection, asymmetric engraftment rate) are statistically very rare. Oil cysts may form — with micro-bolus technique extremely rare and usually asymptomatic. No capsular fibrosis, no BIA-ALCL, no rupture — these are implant issues that disappear here.
Yes — for strongly relaxed tissue the combination of mastopexy + autologous fat augmentation is often the best solution. Dr. Fetai decides anatomically honestly in the consultation: sometimes fat alone is enough, sometimes not.
After 6 months the result is stable. If then more volume is wanted, a second session is unproblematically possible. Reduction is significantly harder (engrafted fat behaves like normal tissue) — therefore: Dr. Fetai doses conservatively and discusses realistic expectations in detail.
Four biological and aesthetic arguments — when anatomy allows, fat is the elegant choice.
Autologous fat feels like breast tissue — because it becomes one. No "silicone edge" to touch, no knot.
Fat is harvested where you don't want it (abdomen, hips) — and transferred to the breast. One OP, two zones improved.
No MRI issues. No capsular fibrosis. No planned follow-up surgeries every 10-15 years like implants.
Autologous fat moves with the body, ages with you, feels alive. Silicone stays — even after 20 years — silicone.
Both paths are valid — but for different patients. The honest comparison.
"Your breast should belong to you — not to a manufacturer."
