Taking fat from one part of the body and injecting it to fill a defect left by surgery is routine reconstructive practice. The question survivors ask is whether it wakes anything up. Matched studies have not found higher recurrence, but they are not randomised trials, and the grafted area can produce changes on a mammogram that need to be told apart from a recurrence.
Autologous fat grafting, or lipofilling, corrects contour defects after breast-conserving surgery and mastectomy, improves the look of a reconstruction and softens radiotherapy-damaged tissue. The oncological question is whether the adipose-derived stromal cells in the graft, which secrete growth factors, could stimulate residual tumour cells. The answer so far comes from matched controlled studies rather than randomised trials: a matched controlled study published in Plastic and Reconstructive Surgery in 2016 found no increase in recurrence after lipofilling of the breast, and other case-controlled series have reported the same.
What the evidence does not include is a randomised trial, and the matched designs cannot fully control for who is offered grafting. Two practical points matter more to most people than the theoretical risk. Fat grafting produces fat necrosis and calcification in a proportion of cases, which shows on imaging and can require further investigation to distinguish from recurrence, so the radiology team needs to know it was done. And graft retention is partial and variable, so more than one session is often needed.
Fat grafting enhanced with concentrated adipose-derived stem cells is a separate and less settled question: it adds a cell-processing step that in most jurisdictions turns the procedure into one that requires regulatory approval, and the comparative evidence against conventional grafting is still being argued.
Harvested fat is washed and centrifuged and injected in small aliquots so that each parcel sits within diffusion distance of a blood supply until it revascularises. Retention depends on handling, on the vascularity of the recipient bed, which radiotherapy reduces, and on the volume placed per pass.
