【摘要】 在癌症发生与发展过程中,70%以上的致癌和促癌因素与环境污染和人类行为有密切关系。国际癌症研究中心确认砷、石棉、苯、吸烟、空气污染等都是导致人类癌症的环境污染物,这些污染物可通过空气、水和土壤对环境产生污染从而产生致癌作用。中国癌症高发区的研究显示,亚硝胺、霉菌、黄曲霉毒素、人乳头瘤病毒感染、职业环境空气氡污染、室内燃煤空气污染是导致中国部分地区癌症高发的原因。控制癌症危险因素是降低癌症危害的有效途径。回顾环境污染与中国常见的食管癌、胃癌、肝癌、宫颈癌、肺癌的流行趋势及典型案例,可为癌症人群预防工作提供科学依据。更多还原

【Abstract】 In the process of cancer occurrence and development, more than 70% of the carcinogens and promoters are associatedwith environmental pollution or human behaviors. Arsenic, asbestos, benzene, smoking, air-pollution, etc. have been classified byIARC as environmental pollutants that are carcinogenic to human. Research in some high risk areas for cancer in China shows thatfood contaminated by nitrosamines, fungus and aflatoxin, or infected by human papillomavirus, occupational exposure to air pollutedby radon, and exposure to indoor air polluted by burning smoky coal are causes of cancers It is an effective approach to control therisk factors to reduce the hazards of cancer. The current study reviews the environmental pollution, the epidemic of cancers ofesophagus, stomach, liver, cervix uteri, lung, and their typical cases to provide scientific references for working on cancer prevention.更多还原
