I don't know if I think survival rates are the best metric for judging progress here. The ones I'm most familiar with are melanoma's, but those are also a factor of many things besides treatment options. The only thing I can think of that its a good metric for is 'people not dying'.

I also don't know if 'cancer isn't a single disease' IS well known by everyone. In this crowd perhaps, but certainly not the population at-large.
