Dr. Dean Ornish Talks Cancer Prevention On CNN's 'Larry King Live'

Dr. Dean Ornish appeared on Larry King's CNN show on Saturday to discuss advances in cancer research.

Cancer "often is preventable," Dr. Ornish said. It's not just new drugs or medical treatments that can make a difference, but also "the simple choices that we make in our lives each day" -- what we eat, how much we exercise, whether we smoke, and how much love we get.
