Fat Transfer in Oncoplastic and Reconstructive Breast Surgery
Fat grafting can soften contour defects after breast surgery, but results and the number of procedures vary.
The key things to know
- Some transferred fat is naturally absorbed.
- Several sessions may be needed.
- New lumps still require assessment.
How fat grafting works
The surgeon removes fat by liposuction from an area such as the abdomen or thighs, prepares it, and injects small amounts into selected breast areas. The technique is commonly used to improve dents, contour, or symmetry after reconstruction or breast conservation. It is different from injecting an artificial filler. The amount suitable for transfer depends on the tissue and its blood supply.
What results to expect
Not all transferred fat survives; some is absorbed during healing. More than one session may therefore be needed, and the final result takes time to settle. Fat grafting can help selected defects but cannot always replace an implant or a flap when a large volume is missing. Future weight changes may also affect the transferred tissue and overall breast shape.
Lumps and imaging changes
Fat necrosis, oil cysts, or calcifications can develop after grafting. These are often benign but may need imaging or biopsy to distinguish them from other findings. Tell your breast-imaging team when and where fat was transferred. A new lump should be assessed rather than assumed to be related to the procedure. Donor sites can also have bruising, irregularity, or discomfort.
Safety and timing
The timing is coordinated with cancer treatment, wound healing, and any radiotherapy. Published clinical experience supports use in appropriately selected patients, but individual oncological and surgical assessment remains necessary. Ask about the expected benefit, alternatives, risks, and surveillance. The procedure should be performed by a suitably trained team with access to your cancer history and imaging.
