Jun 16, 2023 · 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.
Agents can also be classified in Group 1 on the basis of sufficient evidence of carcinogenicity in experimental animals supported by strong evidence in exposed humans that the agent exhibits one or more of the recognized key characteristics of human carcinogens.
Sometimes called the WHO “Encyclopedia of Carcinogens,” the IARC Monographs are critical reviews and evaluations of the weight of the evidence that an agent can increase the risk of cancer in humans.
Dec 1, 2023 · 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. Three strains of human papillomavirus (HPV) were split from a larger grouping of HPV strains.
