Ken Burns unravels the mysteries of cancer in PBS film
There's a mystery to cancer, in large part because of fear, that PBS tries to unravel in next week's six-hour documentary "Cancer: The Emperor of All Maladies," which airs over three consecutive nights beginning on March 30. "We're not really honest with each other," filmmaker Ken Burns said. "We know about heart disease. We know about diabetes. We know about other things, but there's a kind of resistance because cancer is so scary."
