致癌物分类
IARC根据对人类和对实验动物致癌性资料，以及在实验系统和人类其他有关的资料(包括癌前病变、肿瘤病理学、遗传毒性、结构—活性关系，代谢和动力学，理化参数及同类的生物因子)进行综合评价，将环境因子和类别、混合物及暴露环境与人类癌症的关系分为下列五类四组：
第一类：致癌
组1，对人类是致癌物。对人类致癌性证据充分者属于本组。如吸烟和二手烟。
第二类：很可能致癌
组心灵鸡汤经典语录励志2，对人类是很可能或可能致癌物。又分为两组，即组2A和组2B。
组2A，对人类很可能(probably)是致癌物，指对人类致癌性证据有限。对实验动物致癌性证据充分。如生产艺术玻璃、常用电吹风的理发师。
第三类：可能致癌
组2B，对人类是可能(possible)致癌物，指对人类致癌性证据有限，对实验动物致癌性证据并不充分；或指对人类致癌性证据不足，对实验动物致癌性证据充分。
第四类：未知
组3，现有的证据不能对人类致癌性进行分类。
第五类：很可能不致癌
组4，对人类可能是非致癌物。
编辑本段致癌物五类明细表
IARC专家组在2010年1月最新报告对834种环境因子和类别、混合物及暴露环境与人类癌症关系评价结果，
其中组1有100种，组1B有68种，组2B有246种，组3有516种，组4有1种。
IARC对化学物质引起人类癌症危险性评价，是目前公认的权威性资料。在要了解某种化
学物的致癌性时，应首先查阅IARC的资料(网址http：193．51．164．11/monoeval/crthgr01．html)。梦到黑蛇
