How in the world does it cause "anal cancer?" Is this post for real? parsy the puzzled and perplexed.

I guess the ol poop chute can only take so much of a pounding before it lets in all kinds of infections,especially if it wasn't designed for that kind of activity.

I believe that cervical cancer is often caused by HPV (Human Papilloma Virus), which women can be exposed to via heterosexual intercourse. Perhaps anal cancer can be caused the same way?

I suppose the human papilloma virus could have something to do with it, analogous to how it causes cervical cancer in women.
