More can be done to protect workers from cancer-causing carcinogens
TORONTO, Oct. 4, 2017 /CNW/ - A new report released today by the Occupational Cancer Research Centre (OCRC) and Cancer Care Ontario has found that thousands of Ontario workers are exposed to cancer-causing hazards in the workplace, with solar ultraviolet radiation, asbestos, diesel engine exhaust and silica contributing to the majority of occupational cancers.
Ontarians spend an average of one-third of their waking hours at work, yet until recently very little research has been done to determine the extent of cancer-causing exposures in Ontario workplaces.
The report, Burden of Occupational Cancer in Ontario: Major Workplace Carcinogens and Prevention of Exposure, profiles 11 priority carcinogens that are well-established causes of cancer and the most common known or suspected carcinogens found in Ontario workplaces. It also highlights opportunities for prevention at the policy level, as well as in workplaces.
"Occupational exposures are associated with a substantial and often overlooked burden of cancer in Ontario. These cancers are almost entirely preventable," says Dr. Paul Demers, Director, Occupational Cancer Research Centre. "The findings in this report will inform evidence-based actions to enhance prevention efforts, particularly in the industries where workers are regularly exposed to carcinogens."
The best opportunity to decrease the burden of occupational cancer is to prevent and control exposure to four key carcinogens: solar ultraviolet radiation, asbestos, diesel engine exhaust and silica.
- Solar ultraviolet radiation: Nearly half a million workers (approximately 450,000) are exposed to solar radiation each year, primarily in the construction and agricultural industries, which causes an estimated 1,400 non-melanoma skin cancer cases annually.
- Asbestos: Fewer than 55,000 workers are exposed to asbestos (the commercial term for six different types of related mineral fibres), but it is the cause of approximately 630 lung cancers, 140 mesotheliomas, 15 laryngeal cancers and less than five ovarian cancers annually in Ontario. Most occupational exposure occurs in construction, primarily due to the maintenance, renovation and modification of existing public, residential and commercial buildings.
- Diesel engine exhaust exposure: Exposure to diesel engine exhaust affects about 301,000 workers and accounts for an estimated 170 lung and 45 bladder cancer cases each year. The burden is highest in the mining industry as well as transportation and warehousing.
- Silica: 142,000 Ontario workers are exposed to fine crystalline silica dusts, primarily in the construction, manufacturing and mining industries, which causes almost 200 lung cancer cases each year.
The report proposes four overarching policy recommendations to help reduce the burden of occupational cancers, which include:
- Strengthening occupational exposure limits so they are up to date, rigorous and based on evidence of health effects;
- Reducing or eliminating the use of toxic substances in the workplace;
- Creating registries of worker exposure to occupational carcinogens for tracking and monitoring purposes; and
- Including construction workers and employers in the Designated Substances Regulation.
"The best way to prevent occupational cancer is through system-level actions that are based on strong evidence," says Alice Peter, Director, Population Health and Prevention, Cancer Care Ontario. "The policy recommendations in this report have been developed with several sectors in mind, and it is our hope that this information will be a call to action for governments, employers and other health and safety organizations to drive change and help prevent future occupational cancers among Ontario workers."

About Cancer Care Ontario:
Cancer Care Ontario equips health professionals, organizations and policy-makers with the most up-to-date cancer knowledge and tools to prevent cancer and deliver high-quality patient care.
It does this by collecting and analyzing data about cancer services and combining it with evidence and research that is shared with the healthcare community in the form of guidelines and standards. It also monitors and measures the performance of the cancer system, and oversees a funding and governance model that ties funding to performance, making healthcare providers more accountable and ensuring value for investments in the system.
Cancer Care Ontario actively engages people with cancer and their families in the design, delivery and evaluation of Ontario's cancer system, and works to improve the performance of Ontario's cancer system by driving quality, accountability, innovation and value.
About the Occupational Cancer Research Centre:
The Occupational Cancer Research Centre (OCRC) investigates cancers caused by work through an applied research program. It is the first research centre in Canada to focus exclusively on occupational cancer. By working to fill the gaps in knowledge, the OCRC uses research findings to inform prevention programs to control workplace carcinogen exposures and to improve the health of workers.
