TED演讲-口语练习：血液测试可以检测出癌症会怎样?

在TED演讲节目中，演讲者清晰的口语表达及其内容的写作手法都是值得我们学习借鉴的。在本期的TED演讲中，演讲者将提出对血液测试检测出癌症的希望。请结合视频内容，开始口语练习吧！

原文及翻译

A million-dollar question is: in an otherwise healthy body made above trillions of cells, how can we zero in on a small group of road cancer cells? We have recently discovered a new class of oranges that are cancer emergent, meaning that they're only expressed in cancer cells and they're not present in healthy cells. You also discovered that some of these RNAs are actually secreted by cancer cells into the blood. 

一个价值百万美元的问题是：在一个由数万亿个细胞组成的健康的身体中，我们如何才能瞄准一小群癌细胞？我们最近发现了一种新的癌症新基因，这意味着它们只在癌细胞中表达，在健康细胞中不存在。你还发现其中一些 RNA 实际上是由癌细胞分泌到血液中的。

So if you created a platform based on detecting these RNAs in the blood and built a powerful AI machine on top of it, to be able to use the detection of these RNAs to actually identify the presence, and more importantly, not just the presence but also type and subtype of cancers as well, so we can detect cancer as early as possible but also informant is biology. 

因此，如果你创建一个基于检测血液中这些 RNA 的平台，并在其基础上构建一个强大的人工智能机器，就可以利用这些 RNA 的检测来实际识别癌症的存在，更重要的是，不仅仅是癌症的存在，还包括癌症的类型和亚型，这样我们就可以尽早发现癌症，而且生物学也是线索。

The more precise way of doing this is to actually build these blot tests into current screening strategies that exist. For example, for breast cancer, you have mammography, and for colon cancer, you have a colonoscopy and fecal tests. So the question is how do blot tests fit into this kind of current regime to actually save lives? And in every cancer, the answer can be different. Blood detection of cancers is not just a hope but it's actually a reality.

更精确的方法是将这些印迹测试实际构建到现有的筛查策略中。例如，对于乳腺癌，你可以进行乳房 X 线摄影，对于结肠癌，你可以进行结肠镜检查和粪便检查。那么问题是，印迹检测如何适应当前的现状，真正挽救生命？对于每种癌症，答案可能不同。通过血液检测癌症不仅仅是一种希望，它实际上是一种现实。
