Colon cancer remains the second-leading cause of cancer death among both men and women in the U.S. On this week's program, we hear about #strongarmselfie, the Twitter campaign to raise awareness and funds for a cure. Gastroenterologist Dr. Paul Limburg explains why the best test for colon cancer is the one you get. Also on the program, physical medicine and rehabilitation specialist Dr. Allen Brown discusses why older adults are as vulnerable as athletes to traumatic brain injury. And we'll have suggestions for choosing palliative care from general internal medicine specialist Dr. Jacob Strand.
