流行病学用于癌症研究的历史虽短,但对癌症病因的深入研究作出了重大贡献。1950、1952年Doll和Hill发表了吸烟与肺癌关系的经典著作;1957年Court Brown和Doll又发表了放射线和白血病的关系的论文以来,流行病学方法在癌症病因研究中日益被重视,1977年国际癌症研究所(IARC)统计,当时全世界正在进行的癌症流行病学科研有900多项。流行病学在癌症病因研究中十分重要,因为只有了解了病因才能采取一级预防措施,即防癌于未然。应用流行病学研究病因,常采用下述步
Although the history of epidemiology for cancer research is short, it has made significant contributions to the in-depth study of the causes of cancer. In 1950 and 1952, Doll and Hill published the classic works on the relationship between smoking and lung cancer; since 1957, Court Brown and Doll published the paper on the relationship between radiation and leukemia, epidemiological methods have been paid more and more attention to the study of cancer etiology. According to statistics from the International Agency for Research on Cancer (IARC), more than 900 cancer epidemiological studies were ongoing throughout the world. Epidemiology is very important in the study of cancer etiology, because only by understanding the etiology can we take primary prevention measures, that is, prevention of cancer. The epidemiological study of the cause, often using the following steps
