I am glad that this was caught early and something was done to take care of it. Sounds like your dr is on top of things which is real good. I am not sure of the keratinizing as I don't remember seeing that on my results. I was also low on the risk factors. In dealing with things as time has gone on we believe it is something in my genes. Keep the positive attitude, it will take you far. I recommend keeping an eye on things in your mouth in the future and if you ever notice anything get it checked out. That is how I caught my recurrence after two yrs. We all have to be vigilent as this stuff is sneaky and can be peristant.
