IARC group 1

<p>IARC group 1 Carcinogens are substances, <a href="/facts/Chemical_mixture/tms8rbmn">chemical mixtures</a>, and exposure circumstances which have been classified as <a href="/facts/Carcinogenic/soH8Y9CE">carcinogenic</a> to humans by the <a href="/facts/International_Agency_for_Research_on_Cancer/Pb8KPyTz">International Agency for Research on Cancer</a> (IARC). This category is used when there is <a href="/facts/Level_of_evidence/1BaXTJHx">sufficient evidence</a> of carcinogenicity in humans. Exceptionally, an agent (<a href="/facts/Chemical_mixture/tms8rbmn">chemical mixture</a>) may be placed in this category when evidence of carcinogenicity in humans is less than sufficient, but when 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.
</p><p>This list focuses on the <a href="/facts/Hazard/09kGfaao">hazard</a> linked to the agents. This means that while carcinogens are capable of causing cancer, it does not take their <a href="/facts/Risk/tbBEDA0V">risk</a> into account, which is the probability of causing a cancer, given the level of exposure to this carcinogen.
The list is up to date as of January 2024.
