A year ago, I was diagnosed with fibrocystic breasts after finding several painful cysts and a fibroadenoma. Testing has shown that the masses are not cancerous. I am, however, 28 and a childhood leukemia survivor, and my paternal grandmother had reoccurring breast cancer. I am in the process of losing around 100 pounds, and I want to wait so do surgery until that is completed. My question is: is mastectomy an option since I am in pain? I'm okay being flat and not interested in reconstruction!
