Genetic testing may also reveal who in a family does not need such intense screening.

She will obtain the appropriate information about you and schedule an appointment for you. Women who carry a fault in BRCA1 or BRCA2 have a high lifetime risk of breast cancer, estimated to be in the range of 30-60%, and a lifetime ovarian cancer risk of about 20%.
