Fat transfer breast augmentation uses liposuction to remove fat from areas such as the abdomen or thighs, then injects it into the breasts. It gives a modest, natural-feeling increase without an implant. In a 2024 review, an average of 58% of the injected fat was retained, so results are smaller and less predictable than with implants.
This guide is part of our breast augmentation overview, which compares all options in full.
What is fat grafting?
Fat grafting breast augmentation moves your own fat to the breasts in small amounts, so it needs enough spare fat and blood supply to survive.
The American Society of Plastic Surgeons (ASPS, US) lists fat transfer as one of the two ways to enlarge the breasts, alongside implants. The surgeon first removes fat with liposuction, processes it, and then injects it in thin layers. Fat needs a blood supply to survive, which is why it’s placed in small amounts rather than as one large volume.
Because the fat comes from your own body, there’s no implant to rupture or replace. On the other hand, the size increase is limited, and some people need more than one session.
Fat transfer vs implants (table)
As a rule, fat transfer breast augmentation suits a modest, natural change; implants suit a larger, more predictable increase.
| Factor | Fat transfer | Implants |
|---|---|---|
| Typical change | Modest; average 300 mL injected per breast in a 2024 review, of which part is lost | Volume chosen in advance |
| US surgeon fee | $5,500 to $9,500 (ASPS 2024) | $4,575 to $8,000 (ASPS 2024) |
| Recovery | Liposuction sites plus breasts | Breasts only |
| How long it lasts | Surviving fat behaves like your own fat and changes with weight | Not lifetime devices; replacement may be needed |
| Main specific risks | Fat necrosis (firm lumps), calcification, oil cysts | Capsular contracture, rupture, rippling, rare BIA-ALCL |
| Suits | Small, natural increase; enough donor fat | Larger increase; slim people with little spare fat |

Results and fat survival rate
Final fat transfer breast augmentation results depend on how much fat survives, which averaged 58% in a large review but varied widely.
A 2024 systematic review in Plastic and Reconstructive Surgery pooled 35 studies with 3,757 women followed for an average of about two years. Its findings:
- Average fat injected: 300 mL (range 134 to 610 mL)
- Average volume retained: 58% (range 44% to 83%), higher when fat was combined with platelet-rich plasma or stromal vascular fraction
- Overall complication rate: 27.8%, with fat necrosis making up 43.7% of complications
- On imaging: fat necrosis in 9.4% and calcification in 1.2%
- Patient satisfaction at one year: 92% on average
The authors’ title calls for “clinical caution.” A 2019 review in the Chinese Medical Journal also found that retention figures vary with how volume is measured, from under 40% to over 80%, and called for a standard method. Fat necrosis and calcification can show up on breast imaging, so tell your radiologist about the procedure before screening.
In my practice, I explain to patients that the volume they see in the first weeks includes swelling and fat that won’t all survive. The result I ask them to judge is the one at several months.
Candidates and cost
Good candidates want a modest increase, have enough fat to harvest and accept that a second session may be needed.
You may be suited to fat grafting if you:
- Want a modest increase rather than a large change
- Have enough fat in areas such as the abdomen, flanks or thighs
- Have reasonably firm breast skin without significant sagging
- Prefer not to have an implant
- Have a stable weight
ASPS reports an average surgeon fee of $5,719 for fat-grafting augmentation (2023), compared with $4,875 with implants, and a 2024 range of $5,500 to $9,500. Anesthesia, facility and other costs are extra, and insurance generally doesn’t cover cosmetic augmentation. For recovery after augmentation, see our breast augmentation recovery timeline.
Frequently Asked Questions
FAQ
Answers on how much bigger fat transfer makes breasts, permanence, lumps, mammograms and slim patients.
How much bigger can fat transfer make my breasts?
Usually a modest amount. In a 2024 review, surgeons injected about 300 mL per breast on average and around 58% was retained. The final change depends on how much fat you have, how your breast tissue accepts it and whether you have more than one session.
Are fat transfer results permanent?
Fat that survives the first months generally stays and behaves like your own fat. It can shrink or grow if your weight changes, and breasts still age. Some of the injected fat is reabsorbed early, so the result settles over several months.
Can fat transfer cause lumps?
Yes. Fat necrosis, where some grafted fat dies and forms firm lumps, was the most common complication in a large review. Most lumps are benign, but any new lump should be checked by your doctor, and imaging may be needed.
Does fat transfer affect mammograms?
It can. Fat necrosis and small calcifications can appear on breast imaging after grafting. Tell your radiologist about the procedure before any screening so they can compare images and interpret changes correctly.
