Hello all, recently my father in-law has been short of breath, tired and complaining of not feeling well. We urged him to seek a doctors opinion, and the doctor took some blood, did some tests and took a chest x-ray. The results of the chest x-ray showed a "mass" in his left lung. His doctor sent him to Mass General, where they have done a CT and more blood work and he has been admitted to have a biopsy done, we haven't heard much else. I am trying to stay positive I really am nervous that this is lung cancer- I don't know what else it could be the doctors all seem "cautious" about saying anything. I really would like to know if anyone knows more about lung masses than myself (which wouldn't be hard) Thank You Kristen
