Cancer is the second leading cause of death worldwide and most people don't realize they have the disease until they have symptoms.
癌症是世界第二大致死原因，大多数人直到有了症状才意识到自己患上了癌症。
That could change with a blood test called CancerSEEK.
这种情况或许会因为一种名叫“CancerSEEK”的血液检测技术而改变。
This test is designed for people that they have no symptoms，
这个检测是为那些没有症状的病人设计的，
ultimately that is the use that we like therefore this test to have, but the other differences are, one it's a multi-analyte test.
这也是我们希望它具备的，它的另一个不同之处在于它的分析对象不是单一的。
It detects both DNA and protein and that is unique for blood test that they detect multiple type of tumors.
它同时检测DNA和蛋白质，它还可以检测不同类型的肿瘤，这对于血检来说是非常特别的。
Dr. Nickolas Papadopoulos says the test can screen for eight common types of cancer.
尼可拉斯·帕帕佐普洛斯博士说，这项检测可以筛查8种常见癌症。
And it's also unique for its ability to identify the location of the cancer.
而且它还具有识别癌症位置的独特能力。
He and his team at Johns Hopkins Kimmel Cancer Center examined cancer-related DNA and proteins in the blood of more than 1,000 cancer patients.
他和约翰·霍普金斯大学Kimmel癌症中心的团队对一千多名癌症患者的血液进行了检测，针对的是与癌症有关的DNA和蛋白质。
The blood test was positive in about 70 percent of the cases
结果表明，70％的血液检查呈阳性，
and produced only seven false positive results in the control group of 812 healthy people.
在控制组的812名健康人群中，只有7人呈假阳性。
Larger-scale trials are needed, but Papadopoulos says their work could save lives and money.
该测试需要更大规模的试验，但帕帕佐普洛斯说他们的工作可以挽救生命，节省资金。
It's very expensive to treat cancer people with late stage cancer. The drugs are very very expensive.
治疗癌症晚期患者的费用非常高，这些药物非常昂贵。
And we believe that having a screening test to detect cancer individuals that are still feel healthy, they have no symptoms.
对于那些身体依然健康，没有任何症状人群来说，我们希望通过它来检测癌症。
And hopefully the cancer is in very early stages that would be easier to treat,
希望能够早发现，早治疗，
and simple to treat and save their lives compared to just extending their lives.
能够挽救而不仅仅是延长他们的生命。
The researchers hope CancerSEEK will eventually be part of routine health checkups as a way to catch cancer early.
研究人员希望“CancerSEEK”可以最终纳入常规体检，从而实现早发现。
