Using DNA analysis, the BRCA gene test is a blood test utilized to detect changes or mutations in either of the two breast cancer susceptibility genes, those being BRCA 1 and BRCA 2.
Those who inherit mutations in these genes have an increased risk of developing breast and ovarian cancer. Usually, the BRCA gene test isn't tested on individuals who aren't at a heightened risk of breast cancer.
For those who do undergo the test, results aren't always exceptionally clear. A positive result means that you do carry one of the mutations that put you at an increased risk of cancer, but is isn't always the opposite for negative tests. For some, a negative test means that don't carry the mutation. For others, it may mean they carry a mutation that hasn't been discovered yet, or they may have an gene variation that doctors might not be certain about.
BRCA 1 and 2 raise the risk of developing the following cancers:
Breast Cancer
Male Breast Cancer
Ovarian Cancer
Prostate Cancer
Pancreatic Cancer
and Melanoma
For those who carry either of the genes, genetic testing is an option to help you and your loved ones understand the risks associated with the gene you may carry.
