List of IARC Group 1 carcinogens
Substances, mixtures and exposure circumstances in this list have been classified by the IARC as Group 1: The agent (mixture) is carcinogenic to humans. The exposure circumstance entails exposures that are carcinogenic to humans. This category is used when there is sufficient evidence of carcinogenicity in humans. Exceptionally, an agent (mixture) may be placed in this category when evidence of carcinogenicity in humans is less than sufficient but there is sufficient evidence of carcinogenicity in experimental animals and strong evidence in exposed humans that the agent (mixture) acts through a relevant mechanism of carcinogenicity.

Notes
- This evaluation applies to the group of compounds as a whole and not necessarily to all individual compounds within the group.
- Evaluated as a group.
- There is also conclusive evidence that these agents have a protective effect against cancers of the ovary and endometrium.
- Ethanol is not carcinogenic, but is metabolised to acetaldehyde, which is carcinogenic.
- Specific radionuclides for which there is sufficient evidence for carcinogenicity to humans are also listed individually as Group 1 agents.
- There is also conclusive evidence that this agent (tamoxifen) reduces the risk of contralateral breast cancer.

November 2, 2009 ‐‐ IARC has updated the cancer assessments of several personal habits and household exposures that cause cancer, including tobacco, areca nut, alcohol, and household coal smoke. The update was conducted with the advice of 30 scientists from 10 countries who met at IARC in October 2009. [...] The Working Group concluded that acetaldehyde associated with alcohol consumption is carcinogenic to humans (Group 1) and confirmed the classification in Group 1 of alcohol consumption and of ethanol in alcoholic beverages.
