Going through a multiple number of cancers from Hodgkin's, Stomach (which was terminal), Uterus and various skin treatments it was brought out to us that causes of Cancer are either Genetics, Enviromental, or Chemical. It would seem Round Out falls under the chemical category. It is a major challenge to determine which was/is the cause in specific cases. In these cases the best guess was Hodgkins was chemical while stomach was genetic. These were just guesses.
