Quick Summary

A radical mastectomy is a surgical procedure to remove a breast, typically to treat cancer. This surgery involves the removal of the entire breast, the underlying pectoral muscles, and the axillary lymph nodes. It is most effective when cancer is detected early and is localized.1

While a radical mastectomy aims to remove all cancerous tissue, including a margin of surrounding tissue, other types of mastectomies exist. A modified radical mastectomy, for instance, removes the breast but preserves the pectoral muscles. In recent decades, the modified procedure has often been preferred due to similar survival rates and better cosmetic and functional outcomes compared to the standard radical mastectomy. For early-stage breast cancer, a lumpectomy (removing only the tumor) followed by radiation therapy may offer similar benefits with less psychological distress than a radical mastectomy.12
