Work-related cancer is any cancer that results from exposure to cancer-causing agents at work. Cancer-causing agents are also known as carcinogens. Most work-related cancers do not appear until years after exposure to the carcinogen. Even if you were exposed many years ago, your cancer may still be related to your work. Learn more about work-related cancer, the importance of reporting it, what you should do if your cancer is work-related, and the common types and causes of work-related cancer in this brochure.
