“In this case, we had Dr. Fata administering chemotherapy to people who didn’t need it, essentially putting poison into their bodies and telling them that they had cancer when they didn’t have cancer,” said U.S. Attorney Barbara McQuade. “The idea that a doctor would lie to a patient just to make money is shocking.”

Fata made about $35 million as part of a Medicare fraud scheme through his practices in suburban Detroit.

I hate to say it but this is what you get when you have for profit health care; practitioners are paid based on the quantity of health care they deliver, not quality. Frankly I wouldn’t be surprised if this is a common occurrence, maybe not to this degree but doctors have an incentive to cheat their patients as it lines their pockets when they do.
