I am a 4 1/2 year survivor of Stage 1a Adenocarcinoma lung cancer. In November I got a pnuemonia shot from my Dr. I got sick, sinus and upper respiratory infection. This was right before my Cat and Pet Scan. I also have a bleb since original surgery no SUV uptake until this PET. 1.3 value. Surgeon has me on a 3 month recheck which seems resonable to me. Very good Surgeon. My question is on PET they did note that it was consistant with low grade or small tumor or inflamation or infection. Does that ever happen? or is this a nice way of saying it really is cancer and will continue to grow? Once it lites up does he ever just stay at that SUV. or does it just increase. Dr said if it was infection it would be gone in 3 months, but what are the odds that is what it is? any additional information you can give will be greatly appreciated.
