Summary
Brief summary (as posted)
This study will continue to analyze data collected by the Women's Contraceptive and Reproductive Experiences (CARE) study. The CARE study was designed to evaluate the association between reproductive factors and risk of breast cancer in white and African-American women in the United States. The present study is not recruiting additional participants. The original study enrolled 4,575 women with breast cancer and 4,682 control subjects between 35 and 64 years of age All participants provided a blood sample for genetic study. The samples were analyzed for variants (mutations) in the BRCA1 and BRCA2 genes, the vitamin D receptor gene, the androgen receptor gene, and the insulin-like growth factor-1 gene. In addition, all participants were interviewed to obtain information related to breast cancer risk, including a history of reproductive, menstrual, oral contraceptive, and hormone replacement therapy use; lifestyle factors such as smoking, alcohol use, body weight, and physical activity; history of medical conditions and procedures; demographic characteristics, such as age, race, marital status, and so forth; and a detailed family history of cancer.
