Intestinal tract cancers are mostly caused by viruses and bacteria

Most cancers have unknown cause. All digestive tract cancers, whose cause is known, are caused by bacteria or viruses.

Of course that doesn't give the prohibitionists the ammunition they need to ban anything fun.

Reference for "bowel probably cancer caused by viruses":

Reference for "most digestive tract cancers". 60%-70% of of mouth, throat and anal cancer caused by HPV virus:

That's only accounting for 60%-80% of bowel cancers. What about the rest? Well some warts are caused by non-papilloma virus types... maybe they account for some of the rest. Also some digestive tract cancers are associated with Helicobacter Pylori infection. I would bet anyone £10,000 that in twenty years over 80% of bowel cancers will have been proven to be caused by infectious disease. In all likelihood many will be vaccinated against.
