Lot of wrong info i heard on the Corning Monstitutional this week, cancer isn't a disease? I think what he meant was its a "non-pathogenic" disease, as instead of being caused by a foreign invading pathogens, the disease is being caused by the malfunctioning of different organs and tissues, or at this level; individual cells. Cancer, as an umbrella term is very broad and cancers can be caused by many different things, some of them you do have control over. HPV causes cancer and is contagious.
