Breast fat grafting: candidates, results, risks and how to prepare
Breast fat grafting uses the patient's own fat to enlarge or reshape the breast without an implant. This article covers suitability, expected results, risks, imaging considerations and questions to ask a clinic.
Quick answer
Breast fat grafting (fat transfer breast augmentation) enlarges the breast modestly using fat harvested from the patient's own body. It avoids an implant but gives a smaller, less predictable increase, part of the graft is resorbed, and repeat sessions may be needed.[1]
Who is suitable
Healthy adults wanting a small to moderate increase who have enough donor fat. People wanting a large increase or with little body fat may be better served by implants.[1]
Results
Final volume is visible after about three to six months once non-surviving fat is resorbed. Surviving fat behaves like normal fat and changes with body weight.[1]
Risks
- Resorption and volume loss
- Fat necrosis, oil cysts, calcifications visible on mammography
- Asymmetry, infection, rare fat embolism
- Donor-site risks of liposuction
Compared with implants
Implants give predictable size but are not lifetime devices and can rupture or contract.[2] Fat grafting trades predictability for the absence of a device.
Before you book
- Ask how retention is measured and at which time point.
- Ask about sessions, donor site and revision policy.
- If SVF or "stem cell" enrichment is offered, ask about regulatory approval for cell processing and request the evidence.[4]
