Fat necrosis is a condition that can occur after breast surgery, including breast reduction or breast lift procedures. It happens when fatty tissue in the breast loses its blood supply and dies, leading to the formation of firm lumps or areas of scar tissue within the breast. While fat necrosis isn't typically harmful, it can cause discomfort and may affect the appearance of the breast.Here are some common signs of fat necrosis after breast surgery:1. Firm Lumps or Masses: Fat necrosis often presents as firm lumps or masses within the breast tissue. These lumps may feel similar to a breast tumor and can be concerning for patients.2. Pain or Discomfort: Fat necrosis can cause localized pain or discomfort in the affected area of the breast. This discomfort may be persistent or intermittent and can range from mild to moderate in severity.3. Changes in Breast Shape or Size: As fat necrosis heals, it can lead to changes in the shape or size of the breast. This may result in asymmetry between the breasts or alterations in breast contour.4. Skin Changes: In some cases, fat necrosis may cause changes in the overlying skin, such as dimpling, puckering, or retraction. These skin changes can affect the appearance of the breast.5. Imaging Findings: Fat necrosis may be detected on imaging studies, such as mammograms or breast ultrasound. On imaging, fat necrosis may appear as irregular masses or areas of calcification within the breast tissue.It's important to note that fat necrosis is relatively common after breast surgery, including breast reduction or breast lift procedures. The exact incidence of fat necrosis can vary depending on factors such as the surgical technique used, the extent of tissue manipulation, and individual patient characteristics. While fat necrosis can be concerning for patients, it is typically not associated with an increased risk of breast cancer.If you experience signs or symptoms of fat necrosis after breast surgery, it's important to follow up with your plastic surgeon for evaluation and management. In many cases, fat necrosis will resolve on its own over time, but your plastic surgeon may recommend additional imaging studies or interventions if necessary.
