日益增多的证据表明,宫颈癌是由病毒所致。在欧洲,每5000名妇女中每年有1人患宫颈癌。妇科医生常规检查所用的器械也可能传播这种致癌病毒。德意志联邦共和国海德尔堡癌症研究所主任Harald Zur Hausen说,他们在1980年发现的乳头状瘤病毒与两性生殖器疾病有关。有两种病毒与生殖器疣相关。另有两种病毒似与阴茎、外阴和宫颈癌有关。 Zur Hausen说,病毒常见于最先受损的病变部位。有一种致癌病毒能使培养中的包皮细胞“永生”,此作用近似于癌变。然而,瘤细胞有
There is increasing evidence that cervical cancer is caused by the virus. In Europe, 1 in 5,000 women each year develop cervical cancer. The instruments used by the gynecologists for routine examinations may also transmit this carcinogenic virus. Harald Zur Hausen, director of the Heidelberg Cancer Research Institute in the Federal Republic of Germany, said that the pandemic virus they discovered in 1980 was associated with sexual genital diseases. There are two viruses associated with genital warts. There are two other viruses that are related to the penis, vulva, and cervical cancer. Zur Hausen said that the virus is common in the first damaged lesion. There is an oncogenic virus that “immortalizes” foreskin cells in culture. This effect is similar to carcinogenesis. However, there are tumor cells
