In short your report says there is nothing there to make one think you have cancer. It sounds like your lingual tonsils are reacting to something on both sides but one more than the other. Fdg-avid means taking up glucose. This is what cancer does in a pet scan. You show no evidence of malignancy taking up glucose. You also show no enlarged lymph nodes. Sounds like your fighting an upper respiratory infection or allergies. Your pet scan San sounds just like my ct scan I had 6 months ago. Minimum asymmetry in the BOT with no mass and no enlarged nodes.

Sounds like you are in the clear, but I'm not a doctor so best to discuss with them.

I will tell you about an article I just read since I am going through the same exact thing as you right now. I read an article about a woman who had a low grade lymphoma in the base if her tongue that had not spread anywhere else and caused no other symptoms than what you and I are experiencing. Mild BOT swelling. Lymphoma of the lingual tonsil is rare but it does happen. Not saying this to scare you or anything, but you could look it up.

I just read another article where they looked at the mean SUV for areas of the head and neck that weren't cancer and the mean for the lingual tonsils, which is the BOT, was 3.11. That was for non-cancer lingual tonsil uptake.
