Less-invasive mastectomy safe for more breast cancer patients

A less-invasive mastectomy that leaves the surface of the breast intact has become a safe option for more patients, including those whose breast cancer has spread to nearby lymph nodes or who have risk factors for surgical complications, a a new study shows. In the procedure, known as a nipple-sparing mastectomy, surgeons remove breast tissue, leaving the skin, nipple and areola, and immediately rebuild the breasts.
