Define Mastectomy

A mastectomy is the surgical removal of one or both breasts in a patient with breast cancer. The surgery is done to prevent the spread of the cancer.

Partial Mastectomy

• In a partial mastectomy, about 25 percent of the breast is removed. This is suitable for removing small tumors or in early stage cancer.

Total Mastectomy

• In a total mastectomy, the entire breast is removed, along with the skin and nipple.

Modified Radical Mastectomy

• The modified radical mastectomy is the most common type. It consists of a total mastectomy plus removal of the lymph nodes in the armpit. Breast cancer can spread to these axillary lymph nodes

Radical Mastectomy

• A radical mastectomy is similar to a modified radical mastectomy except the muscle lining the chest wall also is removed. This is a drastic procedure which is not done frequently.

Factors Affecting Surgery

• The type of mastectomy performed depends on factors including breast size, cancer stage and whether reconstructive breast surgery is planned afterward.
