The Division of Cancer Epidemiology and Genetics (DCEG) is a National Cancer Institute division focused on identifying cancer causes through epidemiologic and genetic research.
DCEG supports large population studies, biobanks, and biospecimen-driven research that informs risk stratification and biomarker discovery. Its findings influence scientific rationale for prevention trials and targeted screening strategies. DCEG work also informs eligibility criteria and subgroup analyses by clarifying inherited and environmental risk factors. Oversight of sensitive data and specimen use supports ethical governance and participant protections.
