A breast cancer (BRCA) gene test is a blood test that looks for alterations (mutations) in the BRCA1 and BRCA2 genes. This test can determine your risk of developing breast and ovarian cancer. A BRCA gene test does not screen for cancer.
-
BRCA1 and BRCA2 are genes that aid in the regulation of proper cell proliferation. Changes in one of these genes may be inherited. These modifications are known as mutations. If you inherit a BRCA gene mutation, you are more likely to develop breast and ovarian cancers, as well as several other malignancies such as prostate and pancreatic cancer.
-
A negative result indicates that no BRCA gene mutation was discovered, but it does not rule out the possibility of developing cancer in the future.
-
An unclear result indicates that a BRCA gene mutation was found, but it may or may not be associated with elevated cancer risk. If your findings were inconclusive, you may need more testing and/or monitoring.
-
A positive result indicates the presence of a BRCA1 or BRCA2 mutation. These mutations increase your chances of developing cancer. But not everyone with the mutation gets cancer.
