Hereditary Breast and Ovarian tests
Hereditary cancer is where a predisposition to certain cancers is inherited by altered genes. 5-10% of breast cancers are due to an inherited genetic alteration. The alterations most commonly identified in women with hereditary breast cancer are within the breast cancer susceptibility genes, BRCA1 and BRCA2.
BRCA status has significant implications for the therapeutic management of BRCA ovarian carriers. Ovarian cancer patients are tested for BRCA status, regardless of the family history for correct treatment management.
Cancer is complex, as one gene may be responsible for many different cancer types or many genes acting together may increase a woman’s risk of developing breast and ovarian cancer.
