Cancer risks in the workplace can arise from greater exposures to health hazards associated with different types of work. Both workplaces and workers can prevent or control exposures through taking pro-active measures. There is a growing movement towards "zero tolerance to controllable exposures" To take preventive action one needs to consider types of exposures – for instance workers in construction, agriculture, and fishing have greater sun exposure. Manufacturing, mining, firefighters can have greater potential exposure to fossil fuels (such as mineral oils, coal products, benzene, and diesel engine exhaust), asbestos, silica, and solvents. Those involved in foam, paint spray, and car shops have potential exposures to broad range of chemicals (such as isocyanates, TDIs). Many jurisdictions have banned smoking in public and private sectors where workers could be exposed to second hand smoke. At the individual and workplace levels supportive policies can target modifiable risk factors include alcohol abuse programs, reduction in long periods of sedentary work, obesity reduction programs, physical activity initiatives, sun exposure reduction and prevention initiatives, in addition to addressing exposures to chemicals, air pollution, radon gas, etc.
