In many cases of breast cancer, removal of the entire breast is unnecessary. A procedure such as a segmental mastectomy can be performed. In segmental mastectomy, the cancer and a larger area of normal breast tissue around it are removed. Lymph nodes under the arm and the lining over the chest muscles below the tumor also may be removed.
