I am 22 years old now. I do smoke. I just got back from a chest x ray scan, and the doctor told me I got minor lung damager. She told me to either cut down smoking or quit. Straight after that, she approved my checkup as being normal.

So I was thinking to my self, isn’t lung damage a very serious problem? Why did she just approved my checkup to my employer saying that I m normal and not asking me to do another test?

Assuming, if I do stop smoking from now onwards, will the damage lung continue to deteriorate or it might eventually heal back?

Is all smokers’ lung damaged? Should i be getting more examination?
