IARC classifies carcinogens based on the strength of evidence regarding their carcinogenicity in humans and animals. The classification system includes:
Group 1: Carcinogenic to humans. Group 2A: Probably carcinogenic to humans. Group 2B: Possibly carcinogenic to humans. Group 3: Not classifiable as to its carcinogenicity to humans. Group 4: Probably not carcinogenic to humans.
This classification helps policymakers and public health officials in making informed decisions about cancer prevention and control.
