Does expanded genetic testing benefit Jewish women diagnosed with breast cancer?
Full article:

BRCA1 and BRCA2 mutations are common in people of Eastern European (Ashkenazi) Jewish descent. About 2% of all Ashkenazi Jewish people will test positive for one of three common mutations in these genes. Genetic testing for Jewish people sometimes focuses on only the three most common mutations. For Jewish women with breast cancer, little is known about their chance of carrying a different hereditary mutation that may increase risk. This study looked at expanded genetic testing in Jewish women diagnosed with breast cancer to learn how often they carried mutations other than the three most common BRCA gene mutations found in Ashkenazi Jewish people.

Expert Guidelines

The National Comprehensive Cancer Network has guidelines on who should undergo genetic counseling and testing. If you have been diagnosed with breast cancer, you should speak with a genetics expert about genetic testing if any of the following apply to you:     


The American Society of Breast Cancer Surgeons (ASBrS) released guidelines in 2019 that recommend all women diagnosed with breast cancer have access to genetic testing for inherited mutations in breast cancer genes. 

If you are uncertain whether you meet the guidelines above and you are interested in or considering genetic testing, you should speak with a cancer genetics expert
