Most lung cancer is caused by smoking. After you quit, your risk for lung cancer drops gradually. By 10 years, your risk will be about half of what it would have been if you had continued to smoke. This risk continues to decline as the number of years of not smoking increases.1
After you quit smoking, the damage to the lung tissue slows down. In the first days after quitting, you may notice that you cough up more mucus than usual. This is the result of your body trying to clear your lungs. But you will also notice after several weeks that you can breathe more easily, have more stamina, and, eventually, cough less.
