All surgical procedures carry some risks, which will be discussed in detail during consultation. In experienced hands, complications are rare. Possible risks of fat transfer include:
Common risks:
- Temporary swelling, bruising, or tenderness at donor and injection sites.
- Uneven fat absorption or partial loss of volume.
- Small contour irregularities or asymmetry.
- Minor infection or oil cyst formation (rare).
- Scarring — minimal due to tiny incision points.
Rarer risks:
- Fat necrosis — firm nodules due to fat cell loss; usually resolves or can be treated.
- Microcalcifications — small deposits in the breast detectable on mammogram, distinguishable from other findings.
- Fat embolism — extremely rare but serious; minimised by careful technique.
Because no foreign material is used, there is no risk of capsular contracture, rupture, or implant-related conditions such as BIA-ALCL, BIA-SCC, or BII.
