Every year, at least 200 000 people die from cancer related to their workplace, according to the World Health Organization (WHO). Saturday is World Day for Safety and Health at Work. Millions of workers run the risk of developing cancers such as lung cancer and mesothelioma (a malignant cancer of the internal lining of the chest cavity) from inhaling asbestos fibres and from tobacco smoke, or leukemia from exposure to benzene at their workplaces. Yet, the risks for occupational cancer are preventable.

Lung cancer, mesothelioma, and bladder cancer are among the most common types of occupational cancers. Every tenth lung cancer death is closely related to risks in the workplace. Currently about 125 million people around the world are exposed to asbestos at work, and at least 90 000 people die each year from asbestos-related diseases. Thousands more die from leukemia caused by exposure to benzene, an organic solvent widely used by workers, including in the chemical and diamond industries.
