Peridiagnostic and cascade cancer genetic testing

The identification of individuals carrying cancer susceptibility genetic variants could be improved by peridiagnostic cancer genetic testing and cascade testing of the relatives of patients diagnosed with cancer. Herein we discuss two studies that highlight the importance of active involvement of the medical team, both in informing the relatives and offering pre-test telephone genetic counselling.
