Why is cancer on the rise amongst the younger generation? Oprah sits down with world-renowned oncologist, New York Times best-selling author and Pulitzer Prize winner Dr. Siddhartha Mukherjee to find out. In this powerful and deeply personal discussion about the new edition of his groundbreaking book The Emperor of All Maladies: A Biography of Cancer Dr. Mukherjee shares why it was important for him to update his seminal book with four new chapters and what has changed in the science of cancer in the last fifteen years. He explores possible reasons behind the rise of cancer in younger people today including genetic factors, environmental triggers, chronic inflammation and the “sleeper” cells that may lie dormant in the body until activated. Joining the conversation is actress and breast cancer survivor Olivia Munn, wife of the late Chadwick Boseman, Simone Ledward Boseman and a 28-year-old woman from Texas who battled stage 4 endometrial cancer after years of dismissed symptoms. She passed away just weeks after her conversation with Oprah.
