A new genetic1 blood test might pave the way for detecting early stage cancers that often prove fatal when caught too late. The test scans blood for DNA2 fragments released by cancerous tumors.

一项新型验血技术或许可以发现早期癌症,这些癌症往往因发现太晚而导致患者死亡。该验血能扫描出血液中癌性细胞释放出来的DNA片段。

By reviewing these DNA fragments for mutations found in 58 "cancer-driver" genes3, the blood test detects many early stage cancers without rendering4 false positives for healthy people. The test detected stage 1 or 2 colon5, breast, lung or ovarian cancers between 59 percent and 71 percent of the time when assessing 200 patients previously6 diagnosed with cancer. The test also proved capable of screening out cancer-free people.

通过检验58种“致癌”基因中的突变DNA片段,这项验血技术能够检测出很多早期癌症,并且没有误诊健康人士。在对200名已确诊患有癌症的人进行检测时,它检测出1期或2期结肠癌、乳腺癌、肺癌或卵巢癌的概率在59%到71%。这项技术还能够筛选出无癌人士。
