You can visit the nearest pulmonary hospital. When you are old, the operation is very risky. Doctors don't usually take that risk. There are cauliflower-like new organisms in the right middle bronchus of the right lung, which are hard and cannot be taken out. How did the hospital get it? Fiberoptic bronchoscopy seems to have no other minimally invasive surgery except this. If something grows in your bronchi, it's no use trying to remove it with minor surgery. It will take a long time. You should first determine what it is, and then treat it symptomatically.
