John Mansour, M.D.

John Mansour, M.D., is a surgical oncologist on the nationally recognized gastrointestinal cancer team at Simmons Cancer Center. He treats patients with malignancies of the stomach, pancreas, liver, bile duct, and other abdominal organs.

His research focuses on the genetic analysis of tumors and blood, which he hopes will help predict a tumor’s behavior, how aggressive it will be, and how well patients will tolerate a major operation.

In addition to writing articles for the Cancer Answer Line, Dr. Mansour's research has been published in numerous medical journals, including the Annals of Surgical Oncology and Journal of the American College of Surgeons.
