Familial Risk of Cancer and Knowledge and Use of Genetic Testing

MAIN MEASURES: Familial cancer risk was estimated based on the number of first-degree relatives with a breast and ovarian cancer syndrome (BRCA)- or a Lynch-associated cancer, age of onset (<50 or >/=50 years), and personal history of any cancer.
CONCLUSIONS: These nationally representative data provide estimates of the prevalence of familial cancer risk in the US and suggest that information about genetic testing is not reaching many at higher risk of inherited cancer.
