There is no question that the best way to tackle cancer, heart disease, diabetes and the many diseases we all fear is prevention. 

Dr. David Agus says he can help with that and he certainly has the credentials to back it up. He’s one of the world’s leading cancer doctors and pioneering biomedical researchers and specializes in treating patients with advanced cancer.

He’s a professor of medicine and engineering at the University of Southern California and a regular CBS News contributor.  He was Steve Jobs’ doctor and is the author of a fascinating new book called, “A Short Guide to a Long Life.”

He explains how his philosophy to be data-driven in his approach to health has caused him to be labeled as “controversial.” He laments the lack of leadership in this country when it comes to health experts and why he’s frustrated with everyone shilling for products and companies.
