This view, that mental illness is about psychology is kind of like what people refer to as the "god of the gaps" defenses of theism. Far too little is understood about mental illness, but no matter how much we learn about metabolic, autoimmune, or other disorders that affect mental function, there will always be some cases that aren't understood and people will still say that there are psychological explanations. By definition, essentially, mental illness is everything that can't otherwise be classified as a physical or neurological disorder. But all that it is, is a drag on actual efforts to solve problems. As far as comparing to cancer, it seems plausible to me that some measurement like "quality adjusted years lost" (or impaired) could show it's more significant than cancer. I hesitate to say we need more research for anything, because unlimited funding leads to garbage research. But good research is needed. One of the most interesting developments in the last couple decades, I think, was "optogenetics" - techniques that allow scientists to manipulate neurons in a living subject by using light. But just funding more research may just mean torturing a few more mice to no purpose. https://en.wikipedia.org/wiki/Optogenetics https://en.wikipedia.org/wiki/Optogenetics
