Your lungs are self-cleaning, which means they will gradually heal and regenerate on their own after you quit smoking. However, there are certain lifestyle behaviors you can practice to try and accelerate the rate at which your lungs heal.
The mutations that lead to lung cancer had been considered to be permanent, and to persist even after quitting.

The effect has been seen even in patients who had smoked a pack a day for 40 years before giving up.
21 days – Brain biochemistry is returning to normal. 15 days – 90 days – The risk of suffering from a heart attack is starting to decline. Lungs are beginning to recover and your breathing more easily. 20 days – 90 days – Walking is easier and exercising is not a problem it used to be.
Once that tar coating is gone, lungs aren't used to feeling air that only has “normal” particles, like dust or pollen. Once this tar-free tissue is exposed to normal air particles, coughing and shortness of breath can occur.
