Hi Buffalowy, Really not enough information to give any advice. I'm assuming it was a cancer that was confirmed by CT and biopsy? The PET is simply for determining if your cancer has spread to anywhere in the rest of your body. It's a precaution and a test to see. The stage will be determined by all the data gathered by all the tests. Your Doctor will tell you of any stage he feels the data dictates. Hard to wait, I know, but your PET results should clear some questions up for you.
