International researchers have linked 3 genetic regions to an increased risk for lung cancer among Asian women who have never smoked. The finding adds to growing evidence that lung cancer risk among nonsmokers may be associated with genetic factors that distinguish it from lung cancer in smokers. Co-author Stephen J. Chanock, MD, said, “This is an exciting and important paper because it represents the next generation of gene studies better suited to account for environmental exposure.” Read more here.
