From what I understand Cancer seems to thrive on sugars especially processed sugars. You look at Native American tribes, Eskimos, and a lot of other peoples who were, until recently, still living hunter-gatherer style eating a mostly meat-based diet, and you'll see no Cancer at all. Maybe its all just undiagnosed, idk. If anyone is interested I recommend looking into Otto Warburg and Dr. Thomas Seyfried. Seyfried has wrote a book about his hypothesis called "Cancer as a Metabolic Disease," and is now applying modern scientific advances to test Warburg's original hypotheses and challenge the current medical dogma about cancer and how to go about treating it!
