病毒包括DNA和RNA肿瘤病毒,可通过不同机制诱发人恶性肿瘤(癌症)的发生。病毒能直接作用于细胞基因使其增生,最后发展成癌;或是由于机体免疫系统受到抑制,病毒诱发细胞恶性变,形成癌症。后者如艾滋病人由于HIV感染而引起免疫缺陷,很多病人易发生卡波西(Kaposi)肉瘤及淋巴瘤。据现有资料看,EB病毒与鼻咽癌、伯基特淋巴瘤免疫抑制者的淋巴瘤和传染性单核细胞增多症有关;人乳头状瘤病毒与宫颈癌、阴户癌、阴茎癌、肛周癌和皮肤癌有关;HTLV-1
Viruses include DNA and RNA oncoviruses that can induce human malignancy (cancer) through different mechanisms. The virus can directly act on the cellular genes to make them proliferate and eventually develop into cancer; or because the immune system of the body is inhibited, the virus induces the malignant transformation of cells and forms cancer. The latter, such as AIDS people due to HIV infection caused by immune deficiency, many patients prone to Kaposi’s sarcoma and lymphoma. According to available data, Epstein-Barr virus is associated with nasopharyngeal carcinoma, Burkitt lymphoma immunosuppression lymphoma and infectious mononucleosis; human papillomavirus and cervical cancer, vulva cancer, penile cancer, anus Peripheral cancer and skin cancer related; HTLV-1
