Episode 3: Hands of God

Host Mark Shanahan shares a deeply personal, sometimes harrowing, often funny, always true story about prostate cancer, a disease that affects him and millions of other men. With bracing candor and an eye for the absurd, Mark confronts cultural attitudes about masculinity, controversies surrounding screening and treatment, and his own biggest fear: that his diagnosis would wreck the healthy sex life he enjoyed with his wife. Part memoir, part journalistic investigation, Mr. 80 Percent is a heartfelt, hilarious, and helpful resource for men (and their families) touched by this disease.
