Bonnie - Think also about the "good" possibilities - that it is nothing serious. I certainly agree with David - that more questions would be in order. My son recently had an Xray showing "spots" on his lung and this is almost 4 years past end of TX. Then, a CT scan showed the spot was just scar tissue from pneumonia he had last winter. I've also read on this forum that sometimes PET scans can give false positives.
