These lists include only those agents that have been evaluated by the agencies. These agencies tend to focus on substances and exposures most likely to cause cancer, but there are many others that have not been fully studied yet. These lists include agents that have been classified as known or probable human carcinogens.
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).
Substances and exposures that can lead to cancer are called carcinogens. In general, the American Cancer Society does not determine if something causes cancer (that is, if it is a carcinogen ), but we do look to other respected organizations for help with this. When a substance or exposure has been labeled a carcinogen, it means it has been ...
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 (tables 1 and 2). These assessments will be published as part B of Volume 100 of the IARC Monographs.1

Human disease - Carcinogens, Causes, Prevention: Chemicals capable of causing cancer arise from a variety of sources. These include certain synthetic chemicals used in industry, some natural compounds formed during the curing and burning of tobacco, compounds formed during the cooking of meat, and chemicals present in certain plants and molds. Two categories have been identified, those capable ...

Dec 1, 2023 · Note: In September 2022, four additional individual Group 1 agents were created by splitting up some existing agent groupings because not all agents in the groups had the same cancer sites with sufficient and limited evidence for cancer in humans. Three strains of human papillomavirus (HPV) were split from a larger grouping of HPV strains.
