The meaning of carcinogenic to humans

Share:

What does it mean for something to be carcinogenic? What about probably or possibly carcinogenic?

The International Agency for Research on Cancer (IARC) classifies agents into different categories, depending on the strength of evidence that it could cause cancer (which doesn’t mean it WILL cause cancer, just that it CAN). Sufficient evidence shows a clear link between exposure to the agent and cancer (9). Limited evidence suggests a carcinogenic effect, but other explanations like chance, confounding factors or bias can’t be ruled out (9). Inadequate evidence signifies the studies evaluated are too weak, inconsistent, or missing to draw any conclusions (9). Sources: https://tinyurl.com/SUFClassificationIARC Share our original Tweet!
