This is the first time I have ever heard bronchiectasis being identified by stages. I have only heard of it being described in degrees, such as mild, severe, etc. Bronchiectasis is not curable. But it alone will not kill you either. The only problem that those of us who have been diagnosed with it are facing is the possibility of catching other lung-related illnesses because of this condition. I agree with some of the people here that you should seek a second opinion to see if you have other lung-related issues besides bronchiectasis. Many of us here have had bronchiectasis for many, many years and almost all of us have had lung-related illness(es) due to bronchiectasis. Let us know what your pulmonologist say after your appointment. In the meantime, try not to worry or frighten yourself. But we've all been there and can empathize.
