恶性肿瘤是近年来严重危害人类身体健康的常见病之一,由于新兴工业的发展·特别是化工产品的日新月异的和实验室测试手段的现代化,进一步提示了环境中的某些因素可能与肿瘤病因有密切关系,自Pott(1)1775年敏锐的观察到的伦敦的扫烟囱工人,发生了大量的职业性阴囊癌以来,到Higginson(2)1975年于国际肿瘤研究中心里昂讨论会作的“环境因素在肿瘤病因中的重要性”的报告后,二百年来大量的流行病学调
Malignant tumors are one of the common diseases that seriously endanger human health in recent years. Due to the development of new industries, especially the rapid changes in chemical products and the modernization of laboratory testing methods, it further suggests that some factors in the environment may be related to the causes of tumors. There is a close relationship, since Pott (1) in 1775, keenly observed by the chimney sweepers in London, after a large number of occupational scrotal cancers, to Higginson (2) at the International Oncology Research Center Lyon Symposium in 1975.
