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.
