I did a 1 year stint as a LPN going thru their nursing program. During my time on the hospital floor a guy was in there that was a heavy smoker for years. He was in his 50's to 60's He had a tumor/spot on his lung the size of a small lemon. Hate to say this but we did a biopsy but he died within 3 weeks. Here is the kicker back then you could still smoke on hospital grounds and his wife was still smoking. I don't get it. Quit will you can and your lungs can still recover some.
Wow read a couple of threads and see this was posted 2 years ago I surely hope he has quit by now.
Good luck
