I have stage 4 NSCLC Adenocarcinoma lung cancer. I also have developed what is known as Tracheobronchomalacia (TBM). This is a rare condition that occurs when the walls of the airway are weak, which can cause the airway to become narrow or collapse. This makes it very difficult to breath on exertion. As my other side effects from treatment are under control. I feel having this is taking away my quality of life because I basically can't do anything without running out of breath. I have been referred to a Thoracic surgeon but still waiting to hear back on what options I may have. I wanted to put it out there to see if anyone in this group has experienced this and what treatments were they given, and did they work?
