Dr. Dawn Mussallem, DO: Cancer Prevention, Early Detection, Exercise, Metabolic Health and Breast Cancer Screening
In this episode, I’m joined by Dr. Dawn Mussallem, DO, an integrative oncologist, lifestyle medicine specialist, cancer survivor, heart transplant recipient, and the newly appointed Chief Medical Officer of Fountain Life.
We talk about why cancer rates are rising, what we actually know about prevention, and why early detection matters so much when it comes to long-term outcomes. We also discuss the role of exercise, sleep, fiber, metabolic health, toxins, alcohol, gut health, screening tools, mammograms, full-body MRI, liquid biopsies, and why the basics still matter more than most people want to admit.
Dr. Dawn also shares her extraordinary personal story: She is a stage 4 cancer survivor who went through chemotherapy and a bone marrow transplant at 26, developed cardiac toxicity from treatment 18 years later, received a heart transplant, and became the first person in the world to run a marathon within a year of receiving a new heart.
