Occupational cancer is cancer caused by occupational hazards. Several cancers have been directly tied to occupational hazards, including chimney sweeps' carcinoma, mesothelioma, and others.

Common occupational hazards implicated in cancer
Occupational exposure to chemicals, dusts, radiation, and certain industrial processes have been tied to occupational cancer. Exposure to cancer-causing chemicals, also called Carcinogens, may cause mutations that allow cells to grow out of control, causing cancer. Carcinogens in the workplace may include chemicals like anilines, chromates, dinitrotoluenes, arsenic and inorganic arsenic compounds, beryllium and beryllium compounds, cadmium compounds, and nickel compounds. Dusts that can cause cancer leather or wood dusts, asbestos, crystalline forms of silica, coal tar pitch volatiles, coke oven emissions, diesel exhaust and environmental tobacco smoke. sunlight; radon gas; and industrial, medical, or other exposure to ionizing radiation can all cause cancer in the workplace. Industrial processes associated with cancer include aluminum production; iron and steel founding; and underground mining with exposure to uranium or radon.
Other factors that play a role in cancer include:
Occupational cancers
Common cancers and their exposures and occupations include:
Epidemiology
An estimated 48,000 cancers are diagnosed yearly in the US that come from occupational causes; this represents approximately 4-10% of total cancer in the United States. It is estimated that 19% of cancers globally are attributed to environmental exposures (including work-related exposures).
Prevention
Many occupational cancers are preventable. Personal protective gear, workplace controls, and worker education can prevent exposure to carcinogens in the workplace. Tobacco smoking has also been shown to increase the risk of work-related cancers; decreasing or abstaining from smoking can decrease cancer risk.
Agencies like the US Food and Drug Administration, Environmental Protection Agency, and Occupational Safety and Health Administration have developed safety standards and limits for chemical and radiation exposure.
