Are you a 

former smoker?

Lung cancer is the leading cause of cancer death in both men and women, with cigarette smoking causing the great majority of lung cancer cases. Quitting smoking is the only effective way for smokers to reduce their lung cancer risk, though former smokers who have abnormal cells in the lining of their breathing tubes are still at high risk for lung cancer. It is possible that abnormalities in these cells can be reversed with medication.
