Epstein-Barr virus (EBV): EBV belongs to herpes family. It causes Burkitt 's lymplloma. It is a tumor of B-lymphocytes. EBV virus alone cannot cause the tumor. In patients with immune disregulation, EBV causes sustained beta cells proliferation. EBV is found to be closely associated with nasopharyngeal carcinoma.
Hepatitis B Virus (HBV): Hepatitis B virus infection is found to be closely associated with formation of liver cancer.
