First of all, thank you for your reply. I had never heard of this and I was wondering what the deal was. Both parents had lung cancer, so it has been unnerving. Mine was discovered with a baseline CT in January; a followup in May and a petscan in October. Hadn't grown at all, so they will look at it in June. I still have to get in for a lymphnode biopsy (axillary under arm, same side as glass nodule. They told me they could remove it and certainly is my preference, but they want to evaluate. Nodules in thyroid are benign.
