Tom thank you for your response. My pulmonologist met with my thoracic surgeon. they also met within a board meeting of doctors to review my case. This board including my doctors feel that in order to get a definitive diagnosis, they would have to remove the lobe with the nodule in it. They feel I could be in stage 3 cancer because my lymph nodes in thoracic region are also enlarged. I do have a call into an oncologist.
