I went back and re-read my original post and the radiologists report and am not sure I was crystal clear. I think everyone read through my post as intended, but to be sure, the PET report indicated that the moderate uptake was likely negative for cancer, but "technically indeterminate."
As I mentioned, unless I hear something compelling from the 2nd ENT, the course is set to have the surgery next week.
Thanks again all for the helpful input.
