Abstract
Abstract Introduction: Over 90% of breast cancers occur sporadically with no obvious hereditary factors at play, therefore highlighting the need for biomarkers that can identify women who are predisposed to developing breast cancer. DNA methylation of the BRCA1 promoter region is detectable at low levels in the peripheral blood of some women. This phenomenon is referred to as constitutional BRCA1 methylation. Peripheral blood methylation of the BRCA1 gene has been identified as a predisposition factor to the development of BRCA1 methylated tumors. We performed a case-control study to assess peripheral blood BRCA1 methylation from healthy women, and from women with breast cance..
