March is Colorectal Cancer Awareness Month. On the Mayo Clinic Radio podcast, Dr. John Kisiel, a Mayo Clinic gastroenterologist, discusses screening and treatment options for colorectal cancer. Also on the podcast, Dr. Pritish Tosh, a Mayo Clinic infectious disease expert, gives an update on the measles outbreak and flu season. And two Mayo Clinic staff members and friends — Melanie Peterson and Lindsay Stromback — share their story of supporting each other through breast cancer treatment.
