National study finds genetic testing identifies inherited cancer risks in survivors

A national study found that genetic testing can identify inherited cancer risks in survivors diagnosed before such testing was common. The U.K. Retrospective Genetic Testing Program identified eligible breast and ovarian cancer survivors, with 8.6% to 10.1% found to carry cancer-related gene variants. This approach enables personalized follow-up care, earlier screening, and family risk assessment, potentially expanding to other cancer types.
