The Average Cumulative Risks of Breast and Ovarian Cancer for Carriers of Mutations in <i>BRCA1</i> and <i>BRCA2</i> Attending Genetic Counseling Units in Spain

Abstract

These results are consistent with those from a recent meta-analysis of practically all previous penetrance studies, suggesting that women with BRCA1 and BRCA2 mutations attending genetic counseling services in Spain have similar risks of breast and ovarian cancer to those published for other Caucasian populations. Carriers should be fully informed of their mutation- and age-specific risks to make appropriate decisions regarding prophylactic interventions such as oophorectomy.
