MRM stands for Modified radical mastectomy, a surgical abbreviation.

Removal of the entire breast, including the skin over the tumor and the nipple, together with an axillary lymph node dissection, while preserving the chest wall muscles. It replaced the older Halsted radical mastectomy, which also removed the pectoral muscles.

Example: Left MRM for inflammatory breast cancer after neoadjuvant chemotherapy.

Usage notes

Patey and Dyson described a muscle-preserving modification in 1948, and other variants followed. Total (simple) mastectomy removes the breast without axillary dissection and is often paired with sentinel node biopsy. Skin-sparing and nipple-sparing mastectomies allow immediate reconstruction.
