There are minor salivary glands on the roof of your mouth and soft palate. There are some local factors that can cause the findings seen by the pathologist. Smoking, foods, and mouthwashes are just several examples.
Since you are still concerned after two separate biopsies you may consider having the entire lesion excised or ablated with a laser.
HPV is associated with oral cancer but neither of the pathology reports diagnosed you with a papilloma.

To add to that Im concerned because there is nothing obvious that could be causing trauma to the roof of my mouth. I don't wear dentures or anything. I have wore a night guard for teeth grinding for ten years but it sits on my lower teeth and doesn't touch the roof of my mouth.
Being is why the best thing the doctor could come up with is that maybe i breath through my mouth in my sleep and that is causing it. If this did turn into something cancerous would i notice a change in it? It has been virtually unchanged in the 3 and half months its been there.
