Overview
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 susceptibility genes — BRCA1 and BRCA2.
Women who have inherited mutations in these genes are at an increased risk of developing breast cancer and ovarian cancer compared with the general population.
The BRCA gene test is offered only to people who are likely to have an inherited mutation based on personal or family history, or who have a specific type of breast cancer.
The BRCA gene test isn’t routinely performed on women at average risk of breast and ovarian cancers.
A BRCA gene test determines whether you carry an inherited BRCA mutation. If you do, your result is positive and your doctor can help you understand your cancer risk. If you don’t have a mutation, this is considered a negative result.
