The IARC Monographs are a series of scientific reviews that evaluate the carcinogenic risks of various agents, including chemicals, complex mixtures, occupational exposures, physical agents, biological agents, and lifestyle factors. The monographs are widely respected and used by researchers, regulators, and policymakers to make informed decisions about cancer prevention and public health. Each monograph provides a critical review of the available scientific evidence, and agents are classified into one of five groups based on their carcinogenic potential.
