Tobacco and carcinogens in the workplace

Workplace exposures to carcinogens long have been associated with cancers, and corrective measures to limit exposures have resulted in reductions in such cancers and improved worker health. Some exposures are currently of historical interest, and many current or past exposures are associated with conflicting evidence as to causality. We present a brief overview of the effects of exposure to asbestos, tobacco, and other known carcinogens.
