I'm not sure that biting your cheeks will actually cause cancer.. it may be one of those things that doesn't help your chances if something else is a possible cause.
I remember reading a thread on this site about a woman who had a bad habit of biting her cheek when nervous and her dentist told her she really needed to stop because it could lead to cancer. It was a very vague summary of a conversation, so who really knows what he was actually getting at.
It seems possible that if there is a chance of mouth cancer, then having open sores won't help prevent it.
