Thank you for your question. Unfortunately, I am not a spitting kind of gal so bronchoscopy is the only way to find anything with me. I had had MAC for years and it “appeared” to worsen with more and larger nodules so a minimally invasive robotic lung bronchoscopy was scheduled to biopsy a few nodules to see what exactly was growing in my lungs. After years of treatment for MAC ( Big 3 and Arikayce), the MAC was finally gone, but a new invader had taken up residence- aspergillosis fumagatos. Ah the joy of it all! The gift that keeps on giving. Definitely a no bueno, but I have wonderful doctors at UMASS, Worcester, Ma. who put me on a long course of Vfend. ( irene5)
