The more I read about PETscans, the more I wonder. My own PETscan showed "mild hypermetabolic activity" in the upper right lobe of my lung. Went in for a fine needle biopsy a week and a half later, but the contrast ct showed nothing to biopsy.

It seems "hypermetabolic activity" is not always cancer. It could be an inflammatory process.
