"Nope, can't have any cancer cures until we have a disease that is worse to take its place."
I think there are plenty of oncologists who would disagree.
You will have to forgive my scepticism. I worked in the Oncology wing at Richmond Memorial Hospital. I admit that my own experience has made me distrustful of doctors. I go to a family doctor once or twice a year just so I can say I have a doctor in case I have an accident and need repaired. Even then I would probably try to tell them how to set the bones. :)
