中国科学家发现癌症血液快速检测法
Scientists around the world are striving for effective detection of cancer in the early stages, and a Chinese scientist may have found a quick way of knowing whether malignant tumors exist in a patient's body, with just one drop of blood.
全世界的科学家们都在积极探寻早期癌症有效的检测方法，一位中国科学家可能发现了一个快捷方法，仅凭一滴血就可以知道是否病人体内存在这种恶性肿瘤。
Luo Yongzhang and his team in Tsinghua University's School of Life Sciences in Beijing have successfully invented a reagent test kit of Hsp90α for clinical use, which can diagnose multiple kinds of cancer by analyzing a drop of human blood.
Malignant tumors in early phases can be cured but once they have spread all over the patient's body there is no way to save the person's life.
However, it's extremely difficult to be aware of cancer in its early stages, as patients don't show obvious symptoms and thus it can only be found in its later stages, which is already too late, so to detect cancer early remains a global challenge for scientists.
Back in 1989, scientists have found a kind of heat shock proteins (HSP), named Hsp90α, which existed in human bodies and can be used as a cancer biomarker detection kit.
Scientists around the globe have been working on it since then, and more than 10,000 journals have been published on accredited magazines, yet no one has actually turned their research results into medical products.
