On this one, I'm just channeling Dr. Google. Perhaps there will be some posters this weekend who have the real world experience that this board brings to questions. For what it's worth, there were some posts on general lung cancer forums from a patient who had a 25 SUV, and then TX and then had a 19 SUV and he/she was still posting asking questions about was that bad since he/she was still alive. At this point, I think only the biopsy will be able to calm your fears.

Christine's post should bring some comfort. Plus the statistics I've seen show that while the FDG Petscans have super high false positive rates for base of tongue cancer patients, they have extremely good "negative" accuracy. So again, focus on Vince showing no signs of the BOT cancer.
Sorry that i just do not know enough about hot spots in places other than the mouth to give you any more information.
But again, the deficiencies and inaccuracy of FDG petscans is well documented, so there is still hope here.
