与癌症有关的五种危险的环境因素是饮食、酒精、烟草、职业和放射性。专家们估计,在所有由于环境因素导致癌症中,职业这一项占5—10％,目前,人们还不清楚职业导致癌症的每一个因素,因而经常会低估它们的危险。如知道更多的原因,5—10％这个比例还会升高。科学家在进行职业的调查中,到现在已确定有20种致癌物质,其中包括石棉、砷、镉和镍,及其它一些化学物质,如联苯胺、无机油(矿物油)、异丙基乙醇等。有的致癌物质只是与某种癌症有关,如砷可引起肺癌,镉可导致肺癌,联苯安秦可导至膀胱癌,石棉
The five risk-causing environmental factors associated with cancer are diet, alcohol, tobacco, occupational and radiological. Experts estimate that in all cases of cancer caused by environmental factors occupy 5-10%, at present, it is still unclear that occupational leading to each factor of cancer, and therefore often underestimate their risk. If you know more reasons, 5-10% this ratio will increase. So far, scientists have identified 20 types of carcinogens in occupational investigations, including asbestos, arsenic, cadmium and nickel, and other chemicals such as benzidine, mineral oil (mineral oil), isopropyl alcohol and the like . Some carcinogens are only related to some kind of cancer, such as arsenic can cause lung cancer, cadmium can cause lung cancer, biphenyl Ann Qin can lead to bladder cancer, asbestos
