It's worth noting that the most effectives breakthroughs against cancer in recent decades (Immunotherapy, angiogenesis-suppressing drugs) have largely been based on ideas that were first dismissed and widely ridiculed by senior scientists working on cancer research.

I suspect that in another 50 years, when the war against cancer is (finally) over, we will end up with a completely different perspective on the history of cancer research than the often self-serving and propagandized perspective we have today.
