I am not sure what the bumps and things are you are having. My first thought was tori. Which are usually fine and never have to be touched unless you need a denture. They are just bone. Alot of people have them usually under the tongue and some have them on the roof of the month. You could look that up online and see if it's the samething you have. They usually don't biopsy these though cause there are usually not concerns with cancer on these. I don't know.Look up tori
