Nonspecific lung changes

Hi, I am just wondering if anyone else has experienced this scenario w/ a positive outcome. I was first diagnosed 2 years ago at the ripe old age of 31 w/ Stage III colon cancer and had a sigmoid resection followed by 6 mos. of 5-FU/Leukovorin.......at my first followup it was discovered that I had a liver met, luckily for me only one! It was resected last March followed by Camptosar/Xeloda....that finished in August of last summer. I went through the holidays in remission and then went for my second followup on Feb.12......the CT scan showed two "spots" on my right lung, very small, 3-5mm in size. My onc. then ordered a PET scan which came back "clear" - the smallest of the two showing no uptake of glucose, the other showing some, but not what would be expected from a recurrence. Obviously, w/ my history, this is very frightening nonetheless. I can definitely sympathize w/ the women who wrote "crazy thoughts" or something like that.......I loathe the thought of this being a recurrence when I really feel physically wonderful and my life has just really started returning to normal. I am supposed to wait until May then repeat my CT. Have any of you had lung "spots" or scarring that turned up to be non-cancerous?? Any supportive feedback would be greatly appreciated. I am staying "positive" by being in utter and total denial.
