@edivebuddy Hi Edivebuddy! My original pulmonologist just wanted to perform a yearly chest x ray. I told him about the time I was in the service with the coast guard, my relative working construction and being around him for many years and possibly being exposed to that stuff, alot. Being exposed to that stuff plus smoking increases one's chances of developing lung cancer much faster. I decided to drop the pulmonologist and talk to my PA about the history of both and concerned about lung cancer and why he wrote the order for the low dose ct chest scan. Meso is just one of the concerns but lung cancer associated with the other stuff is more prevalent than meso. I am sure my possible cancer case is due to the stuff plus smoking. I am almost certain that I will develop lung cancer presently or near future because the compound affect of the stuff and plus smoking.
