Hazardous Drug Classes
International Agency for Research on Cancer of the World Health Organization (IARC)
IARC Monographs identify environmental factors that can increase the risk of human cancer. These include chemicals, complex mixtures, occupational exposures, physical and biological agents and lifestyle factors. National health agencies use this information as scientific support for their actions to prevent exposure to potential carcinogens.This list includes three categories of substances and processes regarded as carcinogenic by the IARC.
Although there are some differences in categorization, we have combined the lists under a common nomenclature for convenience.
Group 1 is for substances for which there is sufficient evidence for a causal relationship with cancer in humans (confirmed human carcinogen).
Group 2A is for substances for which there is a lesser degree of evidence in humans but sufficient evidence in animal studies, or degrees of evidence considered appropriate to this category, e.g. unequivocal evidence of mutagenicity in mammalian cells (probable human carcinogen).
Group 2B is for substances for which there is sufficient evidence in animal tests, or degrees of evidence considered appropriate to this category (possible human carcinogen).
