Senior Fellow Greg Conko breaks down the fight over Avastin, a drug used to treat several types of cancer. The FDA is poised to rescind Avastin’s approval for treating breast cancer.

Conko believes this battle boils down to one question: who decides which treatments patients can use? Will it be the FDA, or doctors and patients?
