Hi. I have a small white bump on the inside of my mouth, lower right side, on the exact same spot that I used to chew tobacco. I chewed for about a year. The bump is slightly raised. The white part makes it appear puss filled, but that's not the case.

It seems to operate in a two week cycle. It starts out as an almost undetectable mark, grows just a bit and become more raised off the inside of my mouth, and becomes more white in appearance. Eventually it flakes off, appears to be gone, but the cycle repeats. I'm abstaining from alcohol and tobacco now to see if goes away for good but I have my doubts (about it going away, not about my promise to abstain from these vices).

The area surrounding it appears red/white splotchy, doesn't match the side of my mouth where I didn't chew, which appears pink and smooth. Not real bad, but a subtle difference in coloration.

Any advice?
