Classification of agents that are possibly carcinogenic to humans
IARC group 2B substances, mixtures and exposure circumstances are those that have been classified as "possibly carcinogenic to humans" by theInternational Agency for Research on Cancer (IARC) as[ 1] limited evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity inexperimental animals . It may also be used when there is insufficient evidence of carcinogenicity in humans but sufficient evidence in experimental animals. In some cases, an agent, mixture, or exposure circumstance with inadequate evidence of carcinogenicity in humans but limited evidence in experimental animals, combined with supporting evidence from other relevant data, may be included in this group.
This list focuses on thehazard linked to the agents. This means that the carcinogenic agents are capable of causing cancer, but this does not take theirrisk into account, which is the probability of causing a cancer given the level of exposure to this carcinogenic agent.[ 2] [ 3]
