Rarely: The vast majority of lung cancer is thought to be caused by tobacco exposure. A small percentage of the lung cancer cases in non smokers are thought to be hereditary.

See below: There are no defined familial lung cancer syndromes; however, mutations in certain regions of the genome have higher incidence of lung cancer; some inherited changes in metabolic pathway genes may increase risk for carcinogensis from smoking.
