WHAT IS BREAST CANCER (BRCA) SEQUENCING?
The BRCA gene test is a kind of blood test using DNA analysis to identify harmful changes (mutations) in a single one of these two cancers of the breast susceptibility genes — BRCA1 and BRCA2.
Women that have inherited mutations in these genes are near a bigger risk of developing cancer of the breast and ovarian cancer compared with the general population.
BRCA gene test is offered to people, who are likely to get an inherited mutation based on personal or genealogy or which have an important kind of breast cancer. The BRCA gene test isn’t routinely performed on women at average risk of breast and ovarian cancers.BRCA gene test is offered only to people usually likely to get an inherited mutation in accordance with personal or genealogy, or which have an important kind of breast cancer.
