Dr Lesley Walker, director of cancer information at Cancer Research UK who partly funded the research, said smoking was responsible for the vast majority of lung cancers.
"This research shows that inherited genetic variation accounts for some of this risk and the type of lung cancer that develops," she said.
She added: "The best thing a smoker can do to reduce their risk of lung cancer, and a range of other life-threatening conditions, is to quit."
The findings appear in Cancer Research journal.
