'Nother point of interest. They told me I had lung cancer also, based on the PETscan. The upper lobe of my right lung lit up and my RO wanted me to have a lung biopsy before starting chemo. When I went in for the biopsy, whatever was there was gone-there was nothing biopsy.
Everything that lights up under the PETscan is not cancer. There are other infectious/inflammatory processes, especially in a lung.
