A carcinogen is defined as any substance or radiation that promotes cancer formation or carcinogenesis. The agent is possibly carcinogenic to humans. GROUP 2B Acrylamide, Adriamycin. This category is used for agents, mixtures and exposure circumstances for which there is limited evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals. Cooking and processing foods can produce carcinogens. For example, a substance in group C (possible human carcinogen), under the 1986 guidelines, may impart a greater cancer risk to more people than another substance in group A (known human carcinogen), yet there is a greater certainty with regard to the risk associated with the latter. Group 3 These carcinogens do not classify as cancer-causing sources in humans. EPA's first carcinogen risk assessment guidelines [1], published in 1986, were the product of nearly two decades of experience and scientific consensus building. List
Group 1: The agent is ... Group 2B Group 3 . Carcinogens are categorized as “Group 1 when the agent is carcinogenic to humans; Group 2A when the agent is probably carcinogenic to humans; Group 2B when the agent is possibly carcinogenic to humans; Group 3 when the agent is not classifiable as to its carcinogenicity to humans; and Group 4 when the agent is probably not carcinogenic to humans. If you have questions about a medicine that appears on one of these lists, be sure to ask your doctor. Group 2B Due to lack of much evidence, these carcinogens have a relatively low risk of causing cancer in humans but it is still safer to avoid them. Group 2B: Possibly carcinogenic to humans; Group 3: Unclassifiable as to carcinogenicity in humans; Group 4: Probably not carcinogenic to humans ; Perhaps not surprisingly, based on how hard it can be to test these candidate carcinogens, most are listed as being of probable, possible, or unknown risk.
