Detection of occupational carcinogens: completion of an epidemiological study of 14 cancers in all occupations Abstract The carcinogenic risk posed by most occupational exposures is unknown.Medical and exposure histories of 4 000 cancer patients hospitalized in the Montréal area were compared to those of a referent group drawn from the general population.The results indicate an elevated lung cancer risk for workers exposed to nickel, silica, wood dust, and mineral spirits, an elevated bladder cancer risk for workers exposed to synthetic fibres, mineral spirits, and cutting oils, and an elevated stomach cancer risk for workers exposed to gasoline and hydraulic fluids.These findings, taken in conjunction with the exposure profile characteristics of Québec workplaces, should prompt better control of exposure to mineral spirits, hydraulic fluids, mineral oils, and silica.
