   These lists include agents that have been classified as known or probable human carcinogens. The lists do not include substances that have been classified as possible carcinogens, for which the evidence is not as strong. These lists also do not include substances evaluated as “not classifiable as to its carcinogenicity in humans.”

   Are biological agents 'carcinogenic to humans'?

   • In February, 2009, 36 scientists from 16 countries met at the International Agency for Research on Cancer (IARC) to reassess the carcinogenicity of the biological agents classified as “carcinogenic to humans” (Group 1) and to identify additional tumour sites and mechanisms of carcinogenesis ( Table 1, Table 2 ).

   How many agents have been classified as carcinogenic to humans?

   • Since its inception in the early 1970s, the IARC Monographs Programme has evaluated more than 1000 agents with respect to their carcinogenic hazard; of these, up to and including Volume 119 of the IARC Monographs, 120 agents met the criteria for classification as carcinogenic to humans (Group 1).

   Can a non-carcinogenic agent be classified?

   • For agents that have not been classified, no determination of non-carcinogenicity or overall safety should be inferred. See Preventable Exposures Associated With Human Cancers (Cogliano et al., 2011) Read the IARC Monographs Q&A for answers to commonly asked questions on the evaluation process.

   How many carcinogens are there?

   • Perhaps not surprisingly, based on how hard it can be to test possible carcinogens, most are listed as being of probable, possible, or unknown risk. Only a little over 100 are classified in Group 1, as “carcinogenic to humans.” The IARC publishes its findings, including the detailed evidence to support them, in volumes known as monographs.

   The agents are classified as “carcinogenic to humans” (Group 1), “probably carcinogenic to humans” (Group 2A), “possibly carcinogenic to humans” (Group 2B), “not classifiable as to their carcinogenicity to humans” (Group 3), or as “probably not carcinogenic to humans” (Group 4).

   The present analysis of key characteristics of 86 agents classified as carcinogenic to humans (Group 1) by the IARC Monographs Programme was based on mechanistic information retrieved from the IARC Monographs (see Annex 2, by Al-Zoughool et al., and Annex 3, by Birkett et al.). The profiles of key characteristics of these agents show several ...

   genic. Since 1991, IARC has allowed an agent to be classified as carcinogenic to humans if there is sufficient evidence in animal models and “strong evidence in exposed humans that the agent acts through a relevant mechanism of carcinogenicity” [ ( 15 ); sufficient evidence in animal models here means that a causal relationship
