Interdisciplinary working groups of expert scientists review the published studies and evaluate the weight of the evidence that an agent can increase the risk of cancer. 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 400 have been identified as carcinogenic, probably carcinogenic, or possibly carcinogenic to humans.
Read the IARC Monographs Q&A for answers to commonly asked questions on the evaluation process.
The IARC Monographs have received funding from:
- United States National Cancer Institute (Cooperative Agreement 5-U01-CA33193)
- United States National Institute of Environmental Health Sciences
- European Commission Directorate-General for Employment, Social Affairs, and Inclusion (initially from the Unit of Health, Safety and Hygiene at Work, and since 2014 from the European Union Programme for Employment and Social Innovation, EaSI)

IARC Monographs, Volume 100
Review of Human Carcinogens (Package of 6 volumes A,B,C,D,E,F)
25 June 2012 Volume 100 compiles information on tumour sites and mechanisms of carcinogenesis. About half of the agents classified in Group 1 were last reviewed more than 20 years ago, before mechanistic studies became prominent in evaluations of carcinogenicity. In addition, more recent epidemiological studies and animal cancer bioassays have demonstrated that many cancer hazards reported in earlier studies were later observed in other organs or through different exposure scenarios.
