>> "Cancer isn't a single disease" is often shouted from the Dunning-Kruger peak of cancer research.

Literally first phrase on Cancer Wikipedia entry.... [1]

"Cancer is a group of diseases involving uncontrolled cell growth typically resulting in tumors with the potential to invade or spread to other parts of the body...."

Is there something like a meta-Dunning-Kruger, where someone invokes Dunning-Kruger in a way that itself is a potential Dunning-Kruger phenomenon?

I'm inclined to believe that the thing - that everyone intelligent says is complicated - is actually complicated. I would be surprised if the thing - that everyone intelligent says is complicated - is actually simple.

This is almost like an application of the conspiracy theory gambit where you try to find out how many people would have to be "in on it" in order to disprove its likelihood. Like flat earth.

And this business of rates is also why getting the immune system—such as via personalized vaccine—to recognize a tumor is functionally "curing cancer". The problem is it isn't one disease in the sense that different tissues, cell types, and systems are affected leading to different parameters in the design and delivery of said vaccines.
