Uptake of offer to receive genetic information about BRCA1 and BRCA2 mutations in an Australian population-based study

Abstract

Research on the utilization of genetic testing services for mutations in BRCA1 and BRCA2 has focused on women with a strong family history of breast and ovarian cancer. We conducted a population-based case-control-family study of Australian women diagnosed with invasive breast cancer before age 40 years, unselected for family history, and tested for germ line mutations in BRCA1 and BRCA2. Case subjects found to carry a deleterious mutation and their relatives who had given a research blood sample were informed by mail that the study had identified "genetic information" and were offered the opportunity to learn more. Those interested were referred to a government-funded family cancer clinic. ..
