LOS ANGELES, July 2 (Xinhua) -- Exposure to fine particulate air pollution is strongly associated with increased genetic mutations in lung cancer tumors among individuals who have never smoked, a new study led by the U.S. National Institutes of Health (NIH) has found.
The study, published Wednesday in the journal Nature, represents the largest whole-genome analysis to date of lung cancer in nonsmokers, offering new insights into how environmental pollutants may drive cancer in the absence of tobacco use.
