@merpreb My scans are 4 months apart. I'm hoping it is unusual to find the tumor in this shortest period? the problem is I told the doctor not to call me and instead I scheduled an appointment, because last time he called and told me to come in. I waited 1 week thinking I had cancer only to find out it was a residue of the infection. But the downside is I have to wait 4 days to see him on this recent test. I googled the symptoms of lung cancer and I don't have wheezing, blood, pain in arm or chest, cough, weakness but the article also said many people don't have any symptoms early on. I'm hoping if I do have a tumor, it could only be 4 months old and therefore small? so maybe they could successfully remove it?
