A Modified Radical Mastectomy is a surgical procedure used to treat breast cancer. During this operation, the surgeon removes the entire breast along with some of the surrounding lymph nodes, which are small structures that help fight infection. This approach aims to eliminate cancerous tissue while preserving the chest wall muscles. This type of mastectomy is often recommended for patients with invasive breast cancer. It is different from a total mastectomy, where the entire breast is removed without lymph node involvement. Recovery may involve pain management and physical therapy to help regain strength and mobility in the affected area.
