Guest: Samuel Epstein, M.D.

In 1971, Richard Nixon declared war on cancer, but Dr. Samuel Epstein says we have been losing the battle ever since. He says we have made two basic mistakes: we have spent most of our resources on treating cancer once it strikes and have almost ignored prevention. Today on Focus, we'll talk with Dr. Epstein about the future of this medical struggle and his book Cancer-Gate: How to Win the Losing Cancer War.

Guest: Robert Cooke.

Today on Focus, we'll chronicle the life and discoveries of one of the most significant medical figures of our time. Dr. Judah Folkman was the first to hypothesize treatment of cancerous tumors with angiogenesis inhibitors—medicine that would prevent new blood vessels from forming to "feed" the tumor. Today on the show, we're joined by science writer Robert Cooke, the doctor and scientist's biographer and the author of Dr. Folkman's War.
