The Dr.at the hospital after a CT scan of his lungs.
Hi and welcome to the forum. First off, who told you you had a lung nodule? What are your symptoms? How was it discovered?
There are many causes of lung nodules. I had one accidentally noticed on a CT scan of my abdomen, they had me rush into the ER to get a CT of my lungs, and it turned out to be old scar tissue.
If you could give more info, I can try to answer better.
