In this episode we have Dr. William Li, a renowned physician, scientist and author. Dr. Li and Dr. Sanjay discuss how the body has many natural defense mechanisms against cancer. One such defense is DNA, and its ability to suppress cancer cells. Self-care and listening to one's body cannot be overstated in the fight against cancer. Dr. Li urges oncologists to listen closely to their patients to provide the best care. Additionally, small changes in one's diet, like incorporating pears, can improve gut health and affect cancer treatment.
