Causes of cancers are very well known...processed meat, cheese, dairy, and the North American diet that hardly touches fruit and vegetables that should be our staples - not the carcinogen laden foods that are pushed by the Cancer and Diabetes associations themselves (processed meats, red meats, bacon, cheese, eggs, milk, etc.) of course they have to do that because their funding comes from processed food manufacturers.!  Sick people also = big pharma profits.as you are put on 3-12 or more drugs.  Watch the documentary "What the Health"...and "Food, Inc."...put two and two together.  Sick food = sick bodies.
