Excerpt from Canadian Journal of Public Health, 1916 Cancer does not always start in the same way, but it frequently does start in a wart or mole, or a small lump or perhaps a mere scale, or roughness of the skin, or it may start from a blister on the lip where the mouth piece of a pipe presses, or the side of the tongue where the reagh edge of a tooth rubs. It starts very often in some insignificant spot which has been irritated in some way, but it does not always start in the same way nor does it always start from irritation that is unmistakeable and easily recognizable. It may start at some point below the surface of the body or in some gland or some internal organ. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
