I'm going through the same experience you are. I am waiting three months to see if there are any changes.
I had a biopsy and a PET scan, but my doc said it was not conclusive for cancer. Negative, but it does not mean I don't have cancer. PET scan showed moderate activity in the tumor. This may or may not indicate cancer.
I want it removed, but they may take half my lung if they can't find it. No thanks. I'm waiting just three months since it is so small, 10 by 16 mm. I'm looking into Cyberknife as a possibility.
Continue asking questions until you find your answer. You will eventually find what you need.
What size is your nodule?
