Susan, that's interesting to hear. Your docs are suggesting that chronic irritation is the cause, and my docs keep denying it. Glad to hear there are at least some docs out there who acknowledge the possible relationship between chronic irritation & cancer.

I'm trying to find someone to help with the chronic irritation, and hope that I soon find someone who will be able to make an effective mouthguard - the "usual" ones, and even some customized ones, didn't really help enough.
