A new study focuses on the risk non-smokers have of developing lung cancer.

Between 10 and 15 percent of all lung cancers occur in people who have never smoked.

An international team of researchers, led by the American Cancer Society found that non-smoking men are more likely to die of lung cancer than women.

The gender gap also appears to widen as people age.
