I've also had something similar to that, and at first it was biopsied as oral lichen planus .. but then it became dysplasia, so I had it removed with laser. Two years later, after it still hadn't healed, it was again dysplasia, and the oral surgeon at the time wanted to try one more topical ointment before removing it. Next biopsy it was squamous cell cancer. So don't let it go. Be persistent. As Bob said, insist that it be removed, if that's what you have to do.

SCC removed surgically from inside right cheek and commisure 6/03. Margins not clear .. still no sign of recurrence. Also a 10 year thyroid cancer survivor. Would like reconstructive surgery but no one will do it.
