If you have genetic history of breast cancer, you are predisposed to the risk of inheriting it through altered genes. Testing of your genes aims to detect the altered genes, if you have any, to learn your increased susceptibility to breast cancer. This warns you against the breast cancer risk in advance, thereby, helping you to take all the preventive measures.
The test which can determine your breast cancer risk in advance to prevent its occurrence is breast cancer (BRCA) gene test, which has been discussed here in detail.
Breast Cancer (BRCA) Gene Test: is a blood test which detects specific changes called BRCA1 and BRCA2 in genes, however, it is important to note that BRCA is not a diagnostic test for cancer. BRCA gene test is conducted only if an individual has family history of breast cancer.
BRCA1 and BRCA2: A woman is at an increased risk of breast and ovarian cancer if BRCA1 and BRCA2 mutations are seen in her genes. These genetic changes can be inherited from either of maternal or paternal family.
BRCA1 and BRCA2 Carriers
Result of BRCA Gene Testing
Positive: This doesn’t mean that you have breast cancer. A positive result of BRCA1 and BRCA 2 mutation points that you have more than average risk of developing breast cancer over the course of your lifetime.
Negative: In spite of family history of breast cancer, BRCA 1 and BRCA 2 changes haven’t affected your genetic pattern, and you are at the same risk of breast cancer as general population.
BRCA genetic testing does not show all your risk factors of breast cancer. Apart from BRCA gene changes, other factors, such as your lifestyle practices contribute to higher risk of breast cancer.
