During this week\u2019s podcast, we sit down with Mark Lewis, MD, a gastrointestinal oncologist at Intermountain Healthcare. In addition to being a practicing oncologist, Lewis has been living with cancer himself with a hereditary tumor syndrome that\u2019s been passed down in his family, giving him a unique experience that has driven his approach to treating his own patients.\nDuring the interview, Lewis discusses his personal history with cancer, how he\u2019s seen the cancer landscape change over the last 2 decades, and his experience with treating neuroendocrine tumors.
