Ron --

I had false positives with my PET in October. It showed 3 lymph nodes lighting up, but surgeon and RO at the time said that it was probably nothing. PET 10 days ago was fine.

There are so many things that can cause some activity to show up on PET, from exercise the day before the exam, to sugar intake, inflammation, etc.


You are doing the right thing by getting it fully checked out. If it is recurrence, it is very, very early, giving them the most treatment options. If it isn't, then you have gone through a whole lot of anxiety, but the end result is fine.

There are lots of threads on here on PET validity, false positives, etc. They are a real double edged sword -- a negative finding is great, and a positive finding may not mean much, but causes a lot of angst in the meantime. That is why you will read lots of divergent opinions on if and when to use PET or PET/CT. We will all keep a good thought for you.
