Abstract There are three major sources of uncertainties in quantitative cancer risk assessment: low-dose extrapolation, route-to-route extrapolation, and species-to-species extrapolation. Scientific information and procedures useful for reducing uncertainties are discussed. Two examples, one relating to genotoxic carcinogens and another to promoting agents, are presented to demonstrate the importance of incorporating biologic information into the risk assessment. These examples also demonstrate that a quantitative risk assessment is a multidisciplined endeavor that involves various branches of the biomedical and mathematic sciences.
