HealthCentral: How Genetic Testing Works for Breast Cancer

HealthCentral recently interviewed genetic counselor John Lee, associate director of the Genetic Counseling Program at Cedars-Sinai Cancer, about who should consider genetic testing for breast cancer.

Genetic testing typically is recommended for people who are at a higher risk of developing the disease. A family history of breast cancer is one indication of potentially higher risk. The National Comprehensive Cancer Network recommends genetic testing if two or more first-degree relatives (mother, sister or daughter) or multiple distant relatives (grandmother, aunt or cousin) have had the disease.

Lee told HealthCentral that it’s important to consider breast cancer history on both sides of the family, not just on the mother’s side.

“Your dad’s side, such as a paternal grandmother or aunt, is equally important,” he said.

A genetic counselor can help patients determine if they’re good candidates for genetic testing.

To prepare for a genetic counseling session, patients should review their personal and family medical histories. They should speak with relatives to gain a clear picture of which family members developed cancer and at what age they were diagnosed.

“Don’t feel bad if you can’t get access to this info, but finding out as much as possible about your history is beneficial,” Lee told HealthCentral.

Other reasons to consider genetic testing for breast cancer include having a family history of related cancers (such as ovarian, prostate or pancreatic cancer), a personal history of cancer or a current breast cancer diagnosis.

Lee told HealthCentral that genetic testing is often covered by health insurance, but if it isn’t, genetic counselors may have information about programs that can help cover the cost.
