在国际抗癌联盟举办的第21届世界抗癌大会上,国际抗癌联盟主席指出,大约四成的癌症是由三方面因素引起的,即:生活方式因素、传染病等感染因素、职业或环境因素。后两个因素有时候我们个人难以控制,但是第一个致癌因素,只要注意,就可以减少其发生概率。 At the 21st World Anticancer Congress organized by the International Union Against Cancer, the President of the International Union Against Cancer pointed out that about 40% of cancers are caused by three factors: lifestyle factors, infectious diseases, occupational factors, or envirnmental factor. The latter two factors are sometimes difficult for us to control, but the first carcinogenic factor, as long as we pay attention, can reduce its probability of occurrence.
