Which of the following is a direct description of fat necrosis after trauma or breast surgery?

• A. Fat necrosis can occur after trauma or fat injections to augment breast size or fill defects after breast surgery
• B. Fat necrosis only occurs after chemotherapy
• C. Fat necrosis is never associated with radiation therapy
• D. Fat necrosis is always malignant

Answer: (A)

Fat necrosis after trauma or breast surgery is a benign process caused by injury to fat tissue, which can occur with direct chest trauma or with procedures that place or inject fat to augment the breast or fill defects after surgery. When adipocytes are damaged, they release fat that can form oil cysts and later calcifications, with a fibrous scar developing over time; imaging and clinical findings can sometimes mimic breast cancer, which is why this condition is often investigated carefully but is not malignant. This description fits best because fat necrosis is not limited to chemotherapy or excluded by radiation therapy, and it is not inherently malignant.
