kdalda75 makes a good point about second opinion with a pulmonologist with a subspecialty in your disease. I have both lung cancer and pulmonary fibrosis. My first Pulmonologist whose subspecialty is lung cancer sent me to his colleague who specializes in Interstitial Disease for a consult to see if I should be prescribed an antifibrotic (Olev or Esbriet) for my pulmonary fibrosis and dropping lung function test values after radiation treatment. After looking at my records, the colleague thought I might have stabilized and put me on oxygen instead. I have stayed stable for a year now so have not needed an antifibrotic. I have my lung functions tested regularly to stay on top of things.
