Family Variant Testing for Hereditary Cancer
Most cancers develop by chance in an individual and are not due to an inherited cause. However, about 5% to 10% of cancers are thought to be caused by inherited genetic changes (called pathogenic or likely pathogenic variants). These variants can be passed down in families. If your family member tested positive for a pathogenic variant, you may have an increased chance of having the same variant.

If you would like to pursue genetic testing, bring your relative’s genetic test report to an appointment with your healthcare provider. Your provider will review your personal and family history before discussing appropriate genetic test options.
