Can fat necrosis develop into breast cancer?

No: Fat necrosis does not become breast cancer. Sometimes fat necrosis can look concerning enough on a mammogram to be biopsied. The calcifications and scarring from the necrosis can, at times, resemble breast cancer. However, once proven, fat necrosis is a benign diagnosis.

Not at all: Fat necrosis is a result of trauma to the breast, sometimes so minor that you may not even remember the event. Lump develops but usually there is a history of black and blue bruising for a short period of time. Generally, the lump decreases in size over a period of time and disappears entirely, though this may take several weeks or months. There is no risk of cancer.
