Some viruses can induce benign tumors, such as rabbit fibroids virus of the poxviridae family, human infectious molluscum virus and papilloma viruses of the papillomavirus family; some viruses can induce benign tumors, such as rabbit fibers of the poxviridae family Tumor virus, human infectious molluscum virus and papilloma virus of papillomavirus family; some can induce malignant tumors, according to their nucleic acid types can be divided into DNA tumor viruses and RNA tumor viruses. DNA tumor viruses include SV40 and polyoma viruses of the lactopolycystic virus material, as well as certain members of the adenoviridae and herpesvirus families. Viral nucleic acids or fragments and viruses-encoded proteins can be detected from tumor cells, but generally not Complete virions. RNA tumor viruses belong to the retroviridae family, including chicken and mouse leukemia and sarcoma viruses, and virions can be found in tumor cells. Both types of viruses can be transformed into cells in vitro. In human tumors, EB virus has been shown to be closely related to Burkitt's lymphoma and nasopharyngeal carcinoma; recently, retrovirus has been detected from a type of T-cell leukemia. In addition, herpesvirus type 2 may be related to the cause of cervical cancer, and hepatitis B virus may be related to the cause of liver cancer. However, the virus is probably not the only cause, and environmental and genetic factors may play a synergistic role.
