Having fibrocystic disease alone does not necessarily put you at higher risk for cancer. A strong family history of breast cancer or a positive genetic marker might lead you to consider some form of prophylactic procedure like subcutaneous mastectomy. Assuming your physician is an expert in this area, he/she should be able to advise you about your alternatives including careful follow-up alone versus a surgical procedure like a subcutaneous mastectomy.
