The PBS series Cancer: The Emperor of All Maladies promises to be the most comprehensive documentary ever made about the disease. This hour, as part of the KERA Breakthroughs series Growing Up After Cancer, we’ll talk to the film’s director, Barak Goodman, about a future in which the disease is no longer a death sentence. KERA will host a free screening of Cancer: The Emperor of All Maladies tonight. We’d love to see you there.
