Breast cancer now occurs in 1 in 9 women (lifetime risk = 11%). At present only 5-10% of breast cancers can be explained by an inherited mutation in one of the known breast/ovarian cancer genes, known as BRCA1 and BRCA2. Families with 3 or more relatives with breast cancer can be accounted for by mutations in one of these genes and it is now possible to test for mutations in both genes using a simple blood test. Women who are found to have one of the BRCA genes may consider more intense breast screening or even risk reducing surgery (prophylactic mastectomy).

If you would like to find out more about genetic testing for BRCA 1 or BRCA2 please arrange a consultation with one of our breast surgeons.
