Sam S. Yoon, MD

I am a surgical oncologist specializing in the treatment of patients with sarcomas/soft tissue tumors and gastric/gastroesophageal (GE) junction tumors. I received my general surgery training at Massachusetts General Hospital (MGH), completed my fellowship in surgical oncology at Memorial Sloan Kettering Cancer Center, and worked as an academic surgeon at MGH and Harvard Medical School (HMS) for nearly 10 years. While at MGH and HMS, I had a busy clinical practice, ran clinical trials, and led a translational research laboratory. In 2012, I was recruited back to MSK and joined the Gastric and Mixed Tumor Service. I work primarily at MSK’s main campus in Manhattan, and I also spend one morning per week at our Basking Ridge, New Jersey suburban outpatient location where I see patients with sarcomas and gastric cancer as well as patients with tumors of the liver, pancreas, colon, rectum, small intestine, spleen/lymph nodes, and adrenal gland.
