What is BRCA Gene Testing? BRCA gene testing, also known as BRACAnalysis, is a blood test that helps evaluate a personâs risk for developing certain types of breast cancer. The test evaluates two genes, BRCA1 and BRCA2, called breast cancer susceptibility genes.
BRCA testing is a genetic test that looks at the sequence or code of the BRCA1 and/or BRCA2 genes. Changes or mutations in the genetic code indicate increased cancer risks. The test can be performed on a blood or saliva sample.It takes about three weeks to get results. positive test result in BRCA1 or BRCA2 means that the person has a genetic mutation that increases cancer risk. A positive BRCA1 result gives a woman a 60% to 80% lifetime risk of breast cancer and a 30% to 45% lifetime risk of ovarian cancer.
