About FDA

Quantitative Cancer Risk Assessments

Description: Develop and improve strategies for assessing cancer mode actions for quantitative cancer risk assessments.

Definition: It is important for FDA to be able to assess the level of risk for humans exposed to chemicals including food contaminants that are carcinogens. This is done using mathematical models where these models are selected based on the mode by which the chemical causes cancer.

Understanding the potential hazards of dietary supplements and food contaminants as they relate to cancer will provide FDA better information for decision-making in cancer prevention.

Public Health Outcome: This research will improve the cancer risk assessments of dietary supplements and food contaminants.
