1. What is preventive mastectomy, and what types of procedures are used in preventive mastectomy?
Preventive mastectomy (also called prophylactic or risk-reducing mastectomy ) is the surgical removal of one or both breasts in an effort to prevent or reduce the risk of breast cancer. Preventive mastectomy involves one of two basic procedures: total mastectomy and subcutaneous mastectomy. In a total mastectomy, the doctor removes the entire breast and nipple. In a subcutaneous mastectomy, the doctor removes the breast tissue but leaves the nipple intact. Doctors most often recommend a total mastectomy because it removes more tissue than a subcutaneous mastectomy. A total mastectomy provides the greatest protection against cancer developing in any remaining breast tissue.
