Some viruses carry oncogenes that can integrate into the host genome and induce cancer. These are known as viral oncogenes. For instance:
- Human Papillomavirus (HPV): Certain strains of HPV carry oncogenes that can lead to cervical and other cancers. - Epstein-Barr Virus (EBV): This virus is associated with Burkitt's lymphoma and nasopharyngeal carcinoma. - Hepatitis B and C Viruses: Chronic infection with these viruses can lead to liver cancer.
