Exercise tolerance: Hi. If your breathing is better, you can exert yourself, you don't have cough or phlegm coming up, likely your lungs are healthy and will continue to be so as long as you don't restart smoking. You can also get a pulmonary function test if you have any symptoms. In the absence of symptoms, your young age and relatively limited smoking, the pulmonary function tests are highly likely to be normal.

I quit smoking 6 years ago. 2 months ago I relapsed, probably smoked about 10 packs during that time. My question is did I totally negate the healing my body and lungs have made during the 6 years of not smoking? Thank you?

Doctors say lifetime heavy smoking(2packs daily) gives an average 30 percent chance of lung cancer. So a half pack a day gives me 7.5 chance?

Female, 31 yrs old. I smoked a pack of cigarettes a day for 1 year. I have quit and plan on never smoking again. Can my risk for lung cancer eventually become that of a non-smoker? If so, how long will it take?
