Fat necrosis can occur after which events?

Fat necrosis can occur after which events?

• A. After trauma or fat injections to augment breast size or fill defects after breast surgery
• B. After menopause
• C. After chemotherapy
• D. After radiation therapy only

Answer: (A)

Fat necrosis happens when fat tissue in the breast is injured and its blood supply is compromised, leading to cell death and the release of oily material. The most direct and common triggers are blunt trauma to the breast and autologous fat grafting used for augmentation or to fill defects after breast surgery. In both situations, adipocytes can lose perfusion and die, forming oil cysts and sometimes calcifications that can feel like a lump and may mimic cancer on imaging. Menopause or chemotherapy don’t directly cause a focal fat necrosis, and while radiation can lead to fat necrosis as a late effect, the classic and most straightforward scenarios are trauma or fat injections.
