Hi @blm1007blm1007, I'm enrolled in the Encore study at New York University/Langone in NYC. I live in NYC so while it's WAY MORE doctor appointments than I would like to live with, I'm motivated to hit this thing now at age 69, while I'm active & in relatively good health, and am fortunate enough to have access to excellent health care. I do have permanent lung damage but it's mild and not cavitary. I also am on Humira, an immune modulator, for an auto-immune condition and no one wants me to go off that as it has been very helpful for me, but it puts me at higher risk for the MAC to progress, and to progress more quickly. Thus, the recommendation to get treated. So here we are. More folks on immune modulaters (suppressants) get MAC, of course, which is one reason it is starting to get more common, more known and discovered more often and earlier, since so many people are going on these drugs for autoimmune conditions and there is just more testing all-around. Best wishes to you and to all of us!
