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 900 agents have been evaluated, of which more than 400 have been identified as carcinogenic, probably carcinogenic, or possibly carcinogenic to humans.
Meeting 111 is announced.

Volumes 1 to 42 now freely available on-line
21 November 2013
We are pleased to announce that IARC Monographs Volumes 1 to 42 are now available on-line in PDF format. This huge body of work, previously available only in print, represents all evaluations made by IARC Monographs Working Groups between 1972 and 1987.
Volume 109: Outdoor air pollution
23 October 2013
The Working Group for IARC Monographs Volume 109 has classified outdoor air pollution as carcinogenic to humans (Group 1).
A summary of the evaluations has now been published in Lancet Oncology: article; PDF

Call for nominations of agents for review in future IARC Monographs
9 October 2013
IARC encourages the general public, the scientific community, national health agencies, and other organizations, to nominate agents for review in future IARC Monographs. All nominations will be reviewed by the "Advisory Group to Recommend Priorities for the IARC Monographs during 2015-2019", which will meet in Lyon, 7-9 April 2014. For details, please see Upcoming Meetings.
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.
