Study suggests why most smokers don't get lung cancer

Cigarette smoking is overwhelmingly the main cause of lung cancer, yet only a minority of smokers develop the disease.

The findings could help identify those smokers who face an increased risk for the disease and therefore warrant especially close monitoring.
