In many cases, certain types of cancer are associated with specific carcinogens. The table below lists some of these associations.
Please note: This list was complied from information available from reputable sources, but it is not complete. It represents associations that have been reported in literature between certain types of cancer and specific carcinogen exposures.
Exposure to a carcinogen does not necessarily mean that you will develop cancer. The OSH Answers on Occupational Cancer has more information.
