19世纪以前,人们普遍认为肿瘤与生物因素无关,直至1911年Rous肉瘤病毒(Rous′sarcoma virus,RSV)被发现,人们才认识到肿瘤的发生与病毒感染存在一定的相关性[1]。越来越多的研究证明,一些病毒的慢性感染可诱发肿瘤,据国际癌症研究中心估计,全球约20%的人类肿瘤是由病毒所致[2]。这些病毒的致癌机制各有特点,但仍存在某些共性。因此,本文主要对病毒感染与肿瘤发 Until the 19th century, it was generally accepted that tumors were not related to biological factors. Until Rous sarcoma virus (RSV) was discovered in 1911, it was recognized that there was a certain correlation between tumor occurrence and viral infection [1]. More and more studies have shown that chronic infection with some viruses can induce tumors. According to the International Agency for Research on Cancer, about 20% of human cancers in the world are caused by viruses [2]. The carcinogenic mechanisms of these viruses have their own characteristics, but there are still some commonalities. Therefore, this article mainly on the virus infection and tumor hair
