For cancer, there's other research. Google Michael Levin and his morphogenesis research. In short: when an organism grows, it needs to store the intermediate state of its growth somewhere (in the same sense that you have a counter and an end condition in a for loop), and cells need to communicate somehow to coordinate their division and specialization. That somewhere is in electrical potentials between cells. He came to a (sensible) conclusion that cancer occurs when a bunch of cells falls out of this network. And indeed, he was able to induce a tumor in a tadpole, and then make it go away by "plugging" these cells back into the network. It's really fascinating and a bit creepy.
