No. Fat necrosis in the breast is usually the result of tramatic injury. This is also self limited. Surgery to the breast(enhancement, reduction, lumpectomy, biopsy, etc) can result in tissue damage that can manifest as fat necrosis - that is usually self limited. In 20 years, I have seen one patient with fat necrosis in the hip/buttock - that was due to impact trauma. I've not seen it in the breast.
Rare. My only case was related to a nipple piercing, most likely an infectious origin and not true necrosis though. Patient lost 2/3 of her breast.
