And we already know how small a role the cancer gene plays in the onset of cancer: there has been an 8-fold to 17-fold increase in the incidence of cancer in the last hundred years, but not even one-millionth of 1 percent of that increase can be related to genes.

Genes evolve over hundreds of thousands (if not millions) of years, which means that the so-called cancer gene has had no impact on the huge increase we’ve seen since 1900. Virtually 90 percent of the cancer that we see today cannot possibly have anything to do with genes.
