Susan Bhatt

Susan Bhatt leads large-scale epidemiological and clinical studies examining how obesity affects cancer risk, treatment outcomes, and survival across multiple cancer types. Her research demonstrated that obesity at cancer diagnosis is associated with inferior outcomes in breast, colorectal, and endometrial cancer through multiple mechanisms including altered drug pharmacokinetics, immune dysfunction, and pro-inflammatory signaling. She led the first prospective studies showing that intentional weight loss through bariatric surgery reduces cancer incidence and improves cancer treatment outcomes in obese patients. Her work informs oncology guidelines on obesity management in cancer care.
