Mastectomy

Mastectomy of right breast

A mastectomy is the removal of the entire breast. This is called total or simple mastectomy. In a modified radical mastectomy, the breast is removed along with the lymph nodes under the arm, the lining over the chest muscles, and sometimes part of the chest wall muscles.
