Study illuminates origins of lung cancer in never smokers

A genomic analysis of lung cancer in people with no history of smoking has found that a majority of these tumors arise from the accumulation of mutations caused by natural processes in the body. This study describes three molecular subtypes of lung cancer in people who have never smoked. These insights will help unlock the mystery of how lung cancer arises in people who have no history of smoking and may guide the development of more precise clinical treatments.
