My husband has lung cancer. He has had part of his lung removed. Also he has had radiation for colon cancer in the lung. At this point no lung cancer or colon cancer is showing up in the lung on a Pet Scan. There is evidence a part of the lung has collapsed recently which probably is the reason for the increased shortness of breath. He has shortness of breath so that he can get completely out of breath just standing up or walking to the bathroom. He is okay lying down and sitting. His doctor has recommended the Nebulizer. I see a lot of side effects. Can you share your experiences?
