新闻背景:
The tubes are then sent to Owlstone\'s laboratory. There, researchers examined the volatile organic compounds in the breath. Those VOCs, as they are known, are produced by the body\'s normal chemical processes. However, changes in chemical activity can produce particular markings. And those markings can be biomarkers, providing evidence of disease. Some biomarkers may show evidence of cancer in its earliest stages. Cancer develops in stages._____________________________________.One of Owlstone’s founders is Billy Boyle. He says cancer often appears or as he says, “presents” itself after it has spread.然后这些管子被送到奥斯通的实验室。在那里,研究人员检测了呼吸中的挥发性有机化合物。这些挥发性有机化合物,正如他们所知,是由人体正常的化学过程产生的。然而,化学过程的变化会产生特殊的标记。这些标记可以作为生物标记,提供疾病的证据。一些生物标记可能显示出癌症早期的证据。癌症是分阶段发展的。_____________________________________。奥斯通的创始人之一是比利·博伊尔。他说,癌症经常出现,或者像他说的,在扩散后“暴露”自己。
