Besides removing the breast, radical mastectomy is a rarely performed surgery that also takes out lymph nodes in the arm pit and part of the chest wall. See a drawing of the area covered and read a short description.
During a modified radical mastectomy, the surgeon removes the breast (including the skin, breast tissue, areola, and nipple) and most of the lymph nodes under the arm. This surgery is now more commonly performed than the radical mastectomy as it has proven to be more effective and less disfiguring. Learn more about how this surgery is performed.
