The BRCA gene test is a blood test that uses DNA analysis to identify harmful changes (mutations) in either one of the two breast cancer.
While BRCA1 and BRCA2 gene mutations may increase your odds of developing breast cancer, your odds of having either mutation are pretty small. There are also other gene mutations besides BRCA that could increase the risk of breast cancer. Genetic counseling is recommended for those.
Genetic testing gives people the chance to learn if their breast cancer or family history of breast cancer is due to an inherited gene mutation. This section.
