I had the same thing--big tonsil for 3 years. When I went in for my tonsillectomy they had no idea they were going after a tumor. They took the tonsils out. The small one was infected, the big one had a tumor, HPV+. Needless to say, I was shocked with that info coming out of anesthesia. They didn't get clean margins on the tumor since they didn't know they were going in after it. Therefore I needed chemo, radiation, and peg tube. I also got a second opinion--my first doc said one side radiation only, the second doc(Dana Farber)said chemo, and both sides radiation. I didn't enjoy it, but I went with the second opininion. Got through it, and I'm doing fine now. I wish you the best.
