据统计每9个美国妇女中就有一人发生乳腺癌,仅去年几乎就有45,000人死于乳腺癌。遗憾的是目前医生尚无常规程序确定具有哪些症状的妇女是处于该病发病的危险中。但是旧金山的一个研究小组新近报道了一个有发展前途的预测手段:蜕落癌细胞的无痛抽取技术。早在1973年,加州大学的流行病学专家N.L佩特阿克斯吉斯(N.L.Petrakis)及其同事开始征集自愿受试者,进行乳腺癌预测的研究工作。然后在1988年6月到1991年4月间在以前受试者中的87％进行跟踪调查。结果发现,他们中有104人患了乳腺癌。
It is estimated that breast cancer occurs in just one out of every nine U.S. women and in the meantime, almost 45,000 people died of breast cancer last year. Unfortunately, there is currently no routine procedure by a doctor to determine which women have the symptoms of the disease at risk. But a research team in San Francisco recently reported a promising prediction: the painless extraction of cancer cells. As early as 1973, N.L.Petrakis, an epidemiologist at the University of California, and his colleagues began collecting volunteers for breast cancer prediction studies. Follow-up surveys were performed on 87% of previous subjects between June 1988 and April 1991. The results found that 104 of them had breast cancer.
