Can someone please fill me in on what exactly they look for in a Bronchoscopy? Holly had one & the dr left me a vm & basically just said she has some sever inflamation & some mild inflamation. He also said that she had a thick film substance present in the tissue (maybe misunderstood by me) or I think that's what I heard. I am going to call & actually talk to him hopefully next week after the holiday but I thought you can tell everything he just told me from an x-ray or scan so what would be the point of the bronchoscopy tha't more invasive?
