The three DNA viruses found to cause human cancers are EBV, HBV and HPV. What are these? Let us find out.

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.
Human Papilloma Virus (HPV) : HPV gives rise to multiple warts, which are benign squamous papillomas. Some of the warts undergo malignant transformation. Squamous cell carcinoma of cervix has been found to be associated with HPV.
