Hi Rex1 and thanks for the post - excellent question, too! It's one we are all very much concerned about. Even though, at the present time, there is no cure, there is research that is ongoing that seeks to develop one. I thought you might find it both interesting and informative to look over the published material we have here on COPD.net, that focuses on research for COPD: https://copd.net/?s=research. I do hope you find it to be helpful. Wishing you well, Leon (site moderator)
