Occupational exposures increase risk of lung cancer in never-smokers

A recent study published in BMC Cancer demonstrated that exposure at work to potential cancer-causing agents is associated with increased lung cancer risk in the total population and an even higher risk amongst those who have never smoked.

More specifically, never-smokers who were exposed to solvents, paints or thinners, welding equipment or smoke, soot or exhaust (other than tobacco) were approximately two times more likely to get lung cancer than those never- smokers who had not had these occupational exposures.
