    Study Notes

    Oncogenic Viruses

    • Certain viruses can trigger cancer development.
    • RNA viruses associated with cancer include Human T-cell leukemia virus (HTLV-1), which causes adult T-cell leukemia/lymphoma.
    • DNA viruses associated with cancer include Epstein-Barr virus (EBV), which links to Burkitt lymphoma, Hodgkin lymphoma, nasopharyngeal & gastric carcinomas, and Primary CNS lymphoma in immunocompromised individuals.
    • Hepatitis B and C viruses (HBV and HCV) are linked to hepatocellular carcinoma, arising from liver cirrhosis.
    • Human papillomavirus (HPV) causes 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 type 8 (HHV8) is associated with Kaposi sarcoma.

    Bacterial Carcinogens

    • Helicobacter pylori bacteria are linked to gastric adenocarcinoma and gastric lymphomas (MALT).
