Key points
- While there is no single root cause of cancer, there are a wide range of exposures that may contribute to a worker’s risk of cancer, including workplace exposures.
- An estimated 2-8% of all cancers worldwide are caused by exposures to carcinogens (substances known to cause cancer) in the workplace.
- Cancers that occur due to workplace exposures can be prevented.
Overview
There are a wide range of exposures that may contribute to a person’s risk of cancer. This includes but is not limited to:
- Modifiable behaviors, such as tobacco use
- Environmental exposures, such as ultraviolet light
- Infectious agents, such as viruses
- Inherited genetic mutations
- Workplace exposures
Some specific occupations that have been linked to increased cancer risk include:
- Firefighting
- Rubber manufacturing
- Paving
- Roofing
- Painting
- Chimney sweeping

Firefighting Exposures and Cancer
In 2022, an International Agency for Research on Cancer Working Group of experts assembled to re-evaluate occupational exposure as a firefighter as a carcinogen. This webinar gives an overview of the groups decision and evidence to classify firefighting as a human carcinogen (Group I).
