Bobby, I had been dealing with a similar thing for year, but from earlier biopsy I knew it was oral Lichen Planus. After 2 rounds of surgery/rad for separate issue with actual cancer, I managed to burn that particular spot real well and it never really healed up. Decided to have the whole thing removed, and am glad I did. It was nothing cancerous, but there's now no more white or sore patches there and things are back to normal in that area for the first time in maybe 20 years.

Thing was, even after 2 occurances of cancer, the ent still was reluctant to do anything, I finally insisted and said I want it removed that he did anything. A week of mild discomfort was a small price to pay for getting rid of it.
