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.
研究人員通過測(cè)試血液中的腫瘤細(xì)胞DNA，就能在腫瘤被影像術(shù)發(fā)現(xiàn)之前，以更高的精準(zhǔn)度診斷出癌癥。
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.
研究人員說，非常早期的癌癥患者在腫瘤真正形成之前，血液中就會(huì)有腫瘤細(xì)胞的DNA在循環(huán)，這使得疾病的早期治療成為可能。在體層攝影術(shù)、X射線、超聲波或核磁共振等影像術(shù)發(fā)現(xiàn)腫瘤之前，就能在正常的血液樣品中發(fā)現(xiàn)腫瘤細(xì)胞分子。
