In today’s episode, gastrointestinal cancer and prevention specialist, Dr. Andy Chan, explains how changes in the gut microbiome could be to blame.
Dr. Chan discusses the critical role your diet plays in cancer risk, how your gut microbiome can influence the development of colon cancer and the steps you can take to lower your risk.
