Researchers have developed a new way to diagnose cancer with greater accuracy before tumors are detected by using imaging instead of testing for tumor cell DNA in the blood.
研究人员通过测试血液中的肿瘤细胞DNA，就能在肿瘤被影像术发现之前，以更高的精准度诊断出癌症。
Patients with very early stages of cancer have DNA from tumor cells circulating in their blood long before an actual tumor develops, researchers say, which may allow for earlier treatment of the disease. Tumor cell molecules can be discovered in a regular blood sample before a tumor is visible via imaging such as tomography, X-ray, ultrasound or MRI.
研究人员说，非常早期的癌症患者在肿瘤真正形成之前，血液中就会有肿瘤细胞的DNA在循环，这使得疾病的早期治疗成为可能。在体层摄影术、X射线、超声波或核磁共振等影像术发现肿瘤之前，就能在正常的血液样品中发现肿瘤细胞分子。
