Michelle: Know how concerned you are and don't want to raise your fear level. But (you knew a but was coming, right) I was finally diagnosed in 10/03 with cancer of unknown origin due to lymph node lump of 3.5cm. Among other things, a tonsilectomy was performed 11/19/03 and the ENT said he looked at it and was sure no cancer was on either side. They sent it for biopsy just to be sure and ... cancer in right tonsil. Even with the tonsil in his hand, the ENT, a very experienced and trained guy, still couldn't see the tumor. FYI, it was 2.1cm. I would strongly suggest you get someone to get a tissue sample and biopsy the tonsil. I don't know if they can do it with a sonogram directed needle or if a snip is required, but whatever it takes if I were you I would insist on a biopsy. 2 years of sore throat is 23+ months too long in my opinion. Good luck. Regards, Kirk
