The goal of the Burden of Occupational Cancer study is to provide a comprehensive picture of the impact of well-established workplace carcinogens. The carcinogens listed below are also important contributors to occupational cancer burden in Canada.
*Definite human carcinogen = IARC Group 1, probable human carcinogen = IARC Group 2A**Estimates from CAREX Canada
There are smaller numbers of attributable cancers due to the following occupational exposures: acid mists (5 laryngeal cancers, 20 suspected lung cancers), cadmium (5 lung cancers), work as a hairdresser or barber (20 suspected bladder cancers), inorganic lead compounds (15 suspected stomach cancers), and untreated mineral oils (10 non-melanoma skin cancers, <5 melanomas).
The following occupational exposures contribute less than five attributable cancers per cancer site: rubber production (bladder, lung, leukemia, lymphoma, suspected larynx), beryllium (lung), leather dust (sinonasal), vinyl chloride monomer (liver), aromatic amines (bladder), polychlorinated biphenyls (melanoma skin), trichloroethylene (kidney, suspected non-Hodgkin lymphoma, suspected liver), X and gamma radiation (lung, thyroid), 1,3-butadiene (Hodgkin lymphoma, leukemia), tetrachloroethylene (suspected bladder), and art glass manufacturing (suspected lung).
