[单项选择] New Technique Promises Earlier Cancer Detection
A new technique could revolutionize the early detection of cancer, giving sufferers a greater chance of beating the disease, American scientists said. Researchers at the Massachusetts Institute of Technology have devised a novel method of 【51】 changes in the nucleus of cells in the earliest stages of the disease." More than 85 percent of all cancers originate in the epithelium (上皮) that lines the internal surfaces of organs 【52】 the body. Although these are treatable 【53】 they are diagnosed in one of the preventable stages, early body damages are almost 【54】 to detect," said scientist Feld. " We present a new optical-probe (光学探子) technique based on light-scattering spectroscopy (分光镜检查) that is able 【55】 detect precancerous and early cancerous cells in cell-rich epithelia," he added in a statement.
The new technique relies on the fact 【56】 cell nuclei change in the early stages of cancer and the differences scatte
