I had a CT Scan last year, March "06", due to some breathing issues. Turned out to be asthma. This CT Scan showed a 3mm nodular density in the left upper lung and being a 40 year old former smoker I was prety scared. Well, 12 months past and 4 CT scans later this nodule is still unchanged and my Pulminoligist is confident that it is benign. I will need two more CT scans in 6 and 12 months to be 100% certain, but I am no longer worried. I would like to thank the Doctors who run this forum as well as offer this as some reasurance to those who are going through the same thing that I have, it was very scary for a while. GOD Bless!
