I'm 32 years and I have been smoking for last 10 years. Now I wish to quit the habit and I'm trying thru nicotine supplements and by pure control. Though I reduced my cigarettes from 20 to 10, I want to know what damage I have caused to my lungs and respiratory track. What tests should I take to avoid cancer or any deadliest I'll effects due to my smoking? And is there a chance to reset my lungs to it's natural stage? Please tell.

Dear lybrate user. I can understand. You are smoking for last 10 years. Initially, lung cells slowly starts destroying. Damage will be there. You can take a lung function test to ascertain the ill effects of lungs. Your lungs will start repairing itself immediately after you quit smoking. It could take almost one year to complete the process, provided you don't smoke in between again. The risk of cancer will also be lowered. Please quit smoking completely. I suggest deaddiction therapy. Take care.
