What are the 3 main causes of occupational cancer?
Occupational cancer can arise from exposure to many substances or from certain occupational circumstances such as:
- Asbestos fibres (colorectum, larynx, lung, ovary, pharynx, stomach cancers, mesothelioma)
- Wood dusts (nasopharynx, sinonasal cancers)
- UV radiation from sunlight (skin cancers)
How common is occupational cancer?
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).
What is the most common occupational carcinogen?
The most important lung carcinogens in occupational settings are asbestos, radon, arsenic, chromium, silica, beryllium, nickel, cadmium and diesel exhaust. The most important agents for leukaemia are benzene, ionizing radiation and ethylene oxide.
What are the steps we take to determine if something is a carcinogen?
Another important way to identify carcinogens is through epidemiology studies, which look at different groups of people to determine which factors might be linked to cancer. These studies also provide useful information, but they have their limits. Humans don’t live in a controlled environment.
How is occupational cancer diagnosed?
The diagnosis of occupational cancer must be based on a systematic approach in which the diagnosis of cancer is confirmed, the exposures of the patient are defined and quantified, and the scientific evidence regarding the risk from such exposures is evaluated.
Why is it termed as an occupational hazard?
Occupational hazards are risks of illnesses or accidents in the workplace. In other words, hazards that workers experience in their place of work. An occupational hazard is something unpleasant that a person experiences or suffers as a result of doing their job. … It can also mean ‘risk.
Who described occupational cancer?
The outstanding British surgeon Percivall Pott (1714-1789) and the first description of an occupational cancer.
The first recognition that a chemical exposure in the workplace could cause human cancer was the report by Percival Pott in 1775 of an excess incidence of squamous cell carcinoma of the scrotum among young chimney sweeps in London. Pott attributed those tumors to soot.
What type of hazard is a carcinogen?
Carcinogens are agents that can cause cancer. In industry, there are many potential exposures to carcinogens. Generally, workplace exposures are considered to be at higher levels than for public exposures. Safety data sheets (SDSs) should always contain an indication of carcinogenic potential.
Where would you find information to determine if a product or chemical is a carcinogen?
Fortunately, there are several organizations that evaluate the available information according to specific criteria. The most authoritative lists of carcinogens are published by the: International Agency for Research on Cancer (IARC), an agency of the World Health Organization.
Which agents do the IARC classify as Group 1 carcinogenic to humans?

- Acheson process, occupational exposure associated with.
- Acid mists, strong inorganic.
