癌症的发生与地理环境有没有关系?近年来,医学科学工作者带着这个问题,对我国几种主要高发癌症做了大量的地理环境调查研究,其结果令人置信。 在我国,肝癌高发区的地理分布集中在温暖、潮湿的东南沿海地区,其中长江三角洲的发病率比全国任何地区部高,如江苏省启东县。在广东省内,顺德市肝癌的发生率比省内任何地区都高。而肝癌的发病地理分布则没有显著特点,其主要原因是不良生活习惯(如长期大量吸烟)和严重空气污染。
The occurrence of cancer has nothing to do with the geographical environment. In recent years, medical science workers have carried out a large number of geographical environment investigations on several major high-grade cancers in China. The results are convincing. In China, the geographical distribution of high-risk areas of liver cancer is concentrated in the warm and humid southeastern coastal areas. The incidence rate in the Yangtze River Delta is higher than that of any region in the country, such as Qidong County in Jiangsu Province. In Guangdong Province, the incidence of liver cancer in Shunde City is higher than anywhere else in the province. However, the geographic distribution of liver cancer has no significant characteristics, mainly due to bad habits (such as long-term heavy smoking) and severe air pollution.
