First of all, what kind of doctor is treating you. Someone that is an oncologist? Your most recent diagnosis says that you have a very early cancer starting. Not some precancerous change (which is what the rest of the surrounding dysplasia is, and as severe will eventually become one), a cancer. Your first diagnosis, makes no sense at all, since a biopsy would go to a pathology lab, and they would determine that is was something specific, like the finding that it was dysplasia, it was hyperplasia, something specific, but HPV is not one of the choices. That would require a secondary testing of the sample by a different kind of lab (the first one was a histopathology lab) that had PCR or in situ hybridization techniques to determine that specific cells had HPV dna in them, and if they did, what strain of HPV it is�. most are not cancer causing.

So a little more information would be helpful. But removal of something with a laser, while it might be OK in a VERY SMALL carcinoma in situ which is where this is headed, leaves out lots of other things I would want to know. It also does not leave anything behind after the procedure since the tissue is vaporized and the removed part cannot be analyzed further . ( An excised portion would have some of the deeper cells and it might be nice to know that those were not involved.) Did they scan you to determine this is all that is going on? Is all this being done in a dental office by chance? Give us a bit more information to work with and perhaps someone here can give you something more specific as an answer.
