Mastectomy is the removal of the whole breast. There are five different types of mastectomy: "simple" or "total" mastectomy, modified radical mastectomy, radical mastectomy, partial mastectomy, and subcutaneous (nipple-sparing) mastectomy.
Simple or total mastectomy concentrates on the breast tissue itself:
Modified radical mastectomy involves the removal of both breast tissue and lymph nodes:
Radical mastectomy is the most extensive type of mastectomy:
Partial mastectomy is the removal of the cancerous part of the breast tissue and some normal tissue around it. While lumpectomy is technically a form of partial mastectomy, more tissue is removed in partial mastectomy than in lumpectomy.
During nipple-sparing mastectomy, all of the breast tissue is removed, but the nipple is left alone.
