The Alarming New Risks of Cancer Everyone Needs to Hear

"We are all carrying sleeper cells in various organs. But they're dormant, they're asleep, they'll probably do nothing to you for the rest of your life. The new theory is that they need to be woken up—and the sleeping beauty wake-up potion is at least one of them is chronic inflammation."

That is how Dr. Siddhartha Mukherjee, Pulitzer Prize-winning oncologist and author of The Emperor of All Maladies, describes a paradigm-shifting idea now emerging in cancer research. On the Oprah Podcast, he walks through what we actually know about the alarming rise of cancer in younger adults—and what we still don't.

What Cancer Actually Is

Cancer is not one disease. It is a disease of a single cell that can no longer respond to signals telling it to stop growing. Normally, when you cut your hand, wound cells grow back into the wound and then stop. In cancer, those stop signals fail. Genetic mutations produce proteins that cannot receive the "stop growing" instruction, so the cell keeps dividing, forming masses, invading bone and blood, and metastasizing to organs where it has no business being.

But that simple description understates the problem. Cancer cells also hijack other signals that allow them to move, colonize new organs, and survive in hostile environments. It is a cell gone awry in multiple ways at once.

'The Emperor of All Maladies: A Biography of Cancer' by Dr. Siddhartha Mukherjee

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.
