The Occupational Cancer Research Centre (OCRC) hosted a workshop on the classification of carcinogens, held on Tuesday, February 14th, 2012, from 12:00pm – 5:00pm at the United Steelworkers Hall. This workshop aimed to educate and inform attendees on the carcinogen classification process used by the International Agency for Research on Cancer (IARC), highlighting how epidemiological, toxicological and animal studies are used in this process. The classification of shiftwork was used to exemplify the classification procedures employed by IARC. Additionally, the subsequent policy implications of an IARC classification were discussed.
Copies of all workshop handouts are provided below. The Preamble to the IARC Monographs, the Lancet article on shiftwork, and the IARC evidence summary for shiftwork can also be found on the IARC website.
