I had a unique, if cynical, Economics professor way back in the 1970s. One of his favorite whipping posts was the Medical Industry, his ire landing on cancer research and treatment in particular. I can still hear him railing, to wit:

“There is absolutely no intent to find a cure for cancer. If a man announced it tomorrow he’d be face down in the mud the next day. This is about money. This is about the growth of an industry and about jobs and empires.”
Most of us students thought he was a bit nuts. Perhaps, but also perhaps a bit prescient.

For the last 50 years, the same 3 treatments for cancer are used - Chemo/Radio/Surgery. What went wrong?
