The groups have nothing to do with "ranking", they're based on the amount of evidence that we have for the link. From the IARC's FAQ: > The classification indicates the weight of the evidence as to whether an agent is capable of causing cancer (technically called “hazard”), but it does not measure the likelihood that cancer will occur (technically called “risk”) as a result of exposure to the agent. (Emphasis theirs) http://monographs.iarc.fr/ENG/News/Q&A_ENG.pdf |
