BRCA POSITIVE: As many as 10-15% of breast cancers in the us are believed to be hereditary. These are linked to mutations of a particular group of genes called the brca genes. There is a simple blood test to check to see if someone has a brca mutation. I advise my interested patients to see a genetic counselor to fully understand the ramifications of this test before having it done.

Passin abnormal gene: Uncommon, occounting for less than 10% of breast cancers. It is a condition where the susceptability for breast cancer is passed on from a parent to children. The most common genes involved are brca1 and brca2. If there is a strong family history of breast or ovarian cancer, or a diagnosis of breast cancer at a young age, or ashkenazi jewish heritage, the chance for brca positive is higher.

Exception not rule: Most breast cancer diagnoses are not "hereditary". The currently identified mutations (brca 1/2) account for only ~ 10-15% of newly diagnosed breast cancer. The primary risk factors for developing breast cancer are being female and having breast tissue. This is the basis for general population screening including regular self exams, regular clinical exams, and screening imaging (mammography).

BRCA: To determine if you have a hereditary breast cancer, a complete history needs to be obtained. Based on this history and a mapping of your family's cancer history, a brca test may be performed. It is important to determine who in the family should be tested. It is now a saliva test that can be done in a physician office. Genetic counseling is also offered.

Sometimes.: It is estimated that 10-15% of all breast cancer cases in the us occur due to hereditary factors. This risk may be identified by doing a simple blood test to check for brca mutations. We generally advise testing family members with known breast cancers first before checking unaffected family.
