Mahmoud B. El-Tamer, MD - MSK Breast Surgeon

I am a board-certified internist and pulmonologist with a clinical practice dedicated to the prevention and early detection of breast cancer. As clinical director of Memorial Sloan Kettering’s RISE (Risk Assessment, Imaging, Surveillance & Education) Program, I care for thousands of women at increased risk for breast cancer due to such factors as genetic predisposition and family history of the disease, and biopsy results showing atypical cells.

I am a board-certified surgeon with clinical expertise in diagnosing and treating breast cancer. I am investigating the use of exercise to help control weight gain in women who are undergoing chemotherapy and to help prevent lymphedema in women. I am also involved in training young physicians in ways to communicate with patients and their families in a sensitive and productive manner.

I am a board-certified medical oncologist with a practice devoted to treating patients with breast cancer. My laboratory and clinical research both focus on developing new treatment strategies against breast cancers that develop resistance to standard treatments. This involves studies designed to understand the molecular mechanisms underlying resistance and to identify new molecular targets that may inform novel therapeutic approaches.
