  1. IARC group 2B substances, mixtures and exposure circumstances are those that have been classified as "possibly carcinogenic to humans" by the International Agency for Research on Cancer (IARC) as This category is used when there is limited evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals.

  2. Feb 24, 2015 · The IARC Monographs on the Evaluation of Carcinogenic Risks to Humans of the International Agency for Research on Cancer (IARC) are a prominent example of such an expert review process. The goal of the Monograph Programme is to assess carcinogenic hazards from occupational, environmental, and lifestyle exposures and agents, thus providing an ...

    For nearly 50 years, the Monographs program of the International Agency for Research on Cancer (IARC) has been a premier global resource for identifying agents that can cause cancer. The identification of carcinogenic hazards is a necessary initial step in cancer prevention. National and international authorities and organizations use information o...

    Since 2006, substantial growth has occurred in the scientific understanding of factors contributing to carcinogenicity as well as in the development of methods for information gathering, evidence assessment, and integration. In 2018, the IARC convened an “Advisory Group to Recommend an Update to the Preamble,” with broad expertise across multiple d...

    General Procedures

    The advisory group encouraged the IARC to clarify the purpose and scope of the Monographs evaluations. In this regard, the name of the Monographs series has been changed to the IARC Monographs on the Identification of Carcinogenic Hazards to Humans. This change, although semantic in nature, reflects the important distinction between hazard and risk: Hazard refers to the strength of the evidence that an agent is a carcinogen, whereas risk refers to the probability that a given exposure to a ca...

    Scientific Review and Evaluation

    The revised Preamble defines how the principles of systematic review (eg, formal consideration of quality of the studies, such as design and methodology, and the reporting of results that are tailored to each stream of evidence and the types of studies available) apply to IARC assessments and how evaluations are reached to clearly articulate the rationales for expert judgments. At the same time, it is designed to be flexible enough to enable incorporation of further scientific advances as the...

  4. The principles, procedures, and scientific criteria that guide the evaluations are described in the Preamble to the IARC Monographs. Since 1971, more than 1000 agents have been evaluated, of which more than 500 have been identified as carcinogenic, probably carcinogenic, or possibly carcinogenic to humans.

  5. Dec 1, 2023 · Read the IARC Monographs Q&A for answers to commonly asked questions on the evaluation process. 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.

  6. Jun 16, 2023 · IARC Monographs hazard classification. This infographic presents the categories used by the IARC Monographs on the Identification of Carcinogenic Hazards to Humans to classify a substance according to the level of certainty that the substance can cause cancer. This classification does not indicate the level of risk associated with exposure.

  7. One of IARC’s major goals is to identify cancer causes. Its carcinogen grouping system is the most widely used system. The organization has evaluated more than 1,000 likely cancer-causing agents and grouped them into one of four groups. IARC Carcinogen Classifications. Group 1: Carcinogenic to humans.
