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.

诊断期和级联癌症基因检测。

通过诊断前癌症基因检测和对被诊断患有癌症的患者亲属的级联检测，可以改进对携带癌症易感性遗传变异的个体的识别。在这里，我们讨论了两项研究，这些研究强调了医疗团队积极参与的重要性，包括通知亲属和提供测试前电话遗传咨询。
