The Breast Cancer Detection Demonstration Project Follow-up Study involves approximately 64,000 women who were participants in the Breast Cancer Detection Demonstration Project, a 5-year screening program conducted between 1973 and 1980 at 29 centers throughout the United States. The follow-up study began in 1980 and follow-up continued through 2005. Information on cancer diagnoses, benign breast procedures, and exposure to established and hypothesized cancer risk factors has been ascertained through questionnaires administered over the course of the follow-up study. Researchers are analyzing exogenous hormones, lifestyle factors, and other risk factors for breast, ovarian, endometrial, and colorectal cancers.
