Study Notes
Oncogenic Viruses
- Certain viruses are linked to cancer development.
- RNA viruses associated with cancer include:
- Human T-cell leukemia virus (HTLV-1) causing adult T-cell leukemia/lymphoma.
- DNA viruses linked to cancer include:
- Epstein-Barr virus (EBV) causing Burkitt lymphoma, Hodgkin lymphoma, nasopharyngeal and gastric carcinomas, and primary central nervous system lymphoma (in immunocompromised).
- Hepatitis B and C viruses (HBV and HCV) causing hepatocellular carcinoma, starting from liver cirrhosis.
- Human papillomavirus (HPV) causing benign squamous papillomas (warts) and squamous cell carcinomas, primarily in the cervix but also in the vulva, vagina, penis, anus, and oral cavity.
- Herpes virus (HHV8) causing Kaposi sarcoma.
Bacterial Carcinogens
- Some bacteria can also contribute to cancer.
- Helicobacter pylori causes gastric adenocarcinoma and gastric lymphomas (MALT).
