Epidemiology of occupational lung cancer

Occupational risk factors constitute a significant factor for lung cancer risk. The risk of lung cancer is especially increased among workers employed in a number of industries and occupations such as mining, construction, metalworking, and driving. The attributable fraction for lung cancer risk from occupational exposures is reported to be higher in men and an interaction with smoking may occur. Significant occupational carcinogens include asbestos, polycyclic aromatic hydrocarbons including diesel engine emissions, crystalline silica, and some heavy metals. While the burden of occupational lung cancer might have decreased in recent decades, preventive efforts are still needed to further reduce the carcinogenic effects of these exposures.
