Please keep us posted on what you find out. I am in a similar situation. I had a bronchoscopy that was inconclusive and an EBUS that was inconclusive. My mass in the endobronchial tube is 3 cm. PET scan lit up at 13. I was due to have a VATS procedure and the CT scan prior to this showed that the mass had shrunk slightly so the surgeon determined that it was not cancer and they are just keeping an eye on it. However, I am not very comfortable with that.
