It is important to diagnose (诊断) ca

It is important to diagnose (诊断) cancer as early as possible.Some kinds of cancer, however, are especially hard to spot, including cancer of the head and neck.This is why a study published in The Journal of Cancer Research seems to hold good news for cancer diagnosis.The study shows that a tool called Nano Artificial Nose (or shortened to Na-Nose) is able to detect the breath of patients with the head and neck cancer.In other words，Na-Nose can “smell” the head and neck cancer.
Israeli researchers at the Technion-Israel Institute of Technology collected breath samples from volunteers: 22 with various head and neck cancers, 24 with lung cancer，and 36 healthy and cancer-free.The technology of Na-Nose is based on its ability to detect different chemical compounds (混合物) in the breath.The tool is so sensitive that it can tell the difference between people with and without cancer，as well as detecting which patients have the head and neck cancer.
The significance of this study is the possibility of detecting these hard-to-diagnose cancers at an earlier stage, leading to quicker treatment.Lead researcher Professor Hossam Haick said, “There's a desperate need to develop new ways to detect the head and neck cancer because diagnosis of the disease is complicated, requiring specialist examinations.We've shown that a simple breath test can spot the patterns of molecules (分子)which are found in head and neck cancer patients in a small，early study.”
The Journal of Cancer Research，which published the study，is owned by Cancer Research UK.The charity's head of cancer information, Dr.Lesley Walker，said，“It's important to be clear that this is a small study，at a very early stage，so many more years of research with patients will be needed to see if a breath test could be used in the clinic.”

这是重要的诊断（诊断）癌尽早。然而某些种类的癌症，，特别难辨认，包括头部和颈部的癌症。这就是为什么发表在癌症研究杂志的一项研究似乎对癌症的诊断把握好新闻。研究表明，一个工具叫纳米人工鼻（或简称NA鼻子）能够检测患者的呼吸与头颈癌。换句话说，那鼻子可以“闻”的头部和颈部癌症。
在Technion以色列技术收集呼吸样本，从志愿者协会以色列研究人员：22各种头颈癌，肺癌24例，36健康cancer-free.the那鼻子是基于不同的化学成分的检测技术能力（混合物）在呼吸。工具是非常敏感，它可以告诉人们之间的差异没有癌症，以及检测患者的头部和颈部癌症。
本研究的意义是检测这些难以诊断的癌症在早期阶段的可能性，从而导致更快的处理。首席研究员Hossam Haick教授说，“有一个迫切需要开发新的方法来检测头颈癌因疾病诊断复杂，需要专家来诊断。我们已经表明，一个简单的呼吸测试能发现分子模式（分子）被发现在头部和颈部在一个小的，早期的研究中的癌症患者。”
的癌症杂志上的研究，并发表了这项研究，是由英国癌症研究所的癌症信息。慈善的头，莱斯莉沃克博士，说，“显然，这是一个小型的研究是很重要的，在非常早期的阶段，因此，需要更多的研究与患者的研究，以看看是否有呼吸测试可以在临床上使用。
