Halsted radical mastectomy

The Halsted radical mastectomy is a surgical procedure used to treat breast cancer by removing the entire breast, nearby lymph nodes under the arm, and muscle tissue beneath the breast. It was once the standard treatment and aims to eliminate cancer both in the breast and surrounding areas to reduce the chance of recurrence. The surgery is extensive and addresses the spread of cancer beyond the breast tissue itself. Modern treatments often favor less invasive options, but this procedure was a significant development in cancer surgery history.
