The Division of Cancer Epidemiology and Genetics (DCEG) is part of the Intramural Research Program of the National Cancer Institute (NCI) and carries out population-based and interdisciplinary research to discover the genetic and environmental determinants of cancer. Through its broadly based programs in epidemiology, genetics, statistics and related areas, the primary mission of the DCEG is to conduct high-quality, high impact research to uncover the causes of cancer and the means of prevention.
