I have just been Dx with a 7 mm nodule in the upper right lung. Only one is detected and I have had a CT with contrast and am having a PET on Monday and have a surgical appointment with specialist on Wednesday. Very frightened. I do not even know if a needle biopsy is possible for the area where this nodule is. There is some calcification but not a lot says the pulmonologist. Very concerned and do not know what to do???
