What is the importance of genetic testing in breast cancer?

Dr. Mehmet Oz, MD

Cardiology (Cardiovascular Disease)

Women with a strong family history of breast cancer (at early ages), should discuss whether they should undergo genetic testing. In some families, family history can be explained by the presence of an error in a gene that you inherit from either your mother or father. A simple blood test can determine whether it is present or not. Family members who carry the gene should undergo more intensive screening, even before age 40, and have yearly mammograms and MRIs, alternating every six months. It is also important to talk to a genetic counselor or a surgeon about options for preventive surgery.

Genetic Testing

Genetic testing looks for evidence that you have a disease, may be more likely to develop a disease or possibly pass on a disease to your children. Testing can be done on samples of hair, skin or blood, and in the case of prenatal testing, amniotic fluid. Genetic testing can also help determine best treatment options.
