If you had had tonsillar cancer 8 years ago and it was untreated until now, you would likely be dead. If he can't see anything to biopsy... what would you have liked him to do? Just cut random pieces off your tonsils, hoping that he hit the jackpot? That would be illogical, painful, and probably malpractice. No one can see an HPV infection in your mouth and there is no way to test for it right now, so no one missed doing anything in your mouth as it related to testing for HPV. A very expensive PCR test would have to be done (genetic testing) and even with that it wouldn't mean that you were going to get an oral cancer. Not all people that get HPV get cancer. You've gone from swollen tonsils to lung cancer in two posts, and talked about death. Think about that. You need to reign in your emotional side until you get some answers, and don't jump to the worst possible situation so early in the game.
