"I would venture that we understand more of the immune system's complexity than any other system in the body" NO - this is a completely and profoundly FALSE statement. We have learned quite a bit about the immune system in the past decade or so but it is still one of the most mysterious systems in the entire body. The immune system is a black box from the standpoint of most clinicians today. It's an _incredibly_ overwhelming and complex system with dozens of interacting cell types and different molecules spewing into our bloodstream; with each of those cells containing tens of thousands of genes whose activity is dependent upon dozens of factors. So it is far from being understood. But the research and technology is promising. Immunologists today still perform the same tests they did in the 1960s outside of advanced and experimental immune studies done at the university level. Your generic explanation of cancers is also incredibly incorrect.
