An oncovirus or oncogenic virus is a virus that can cause cancer. [4] This term originated from studies of acutely transforming retroviruses in the 1950–60s, [5] when the term "oncornaviruses" was used to denote their RNA virus origin. [6]
An oncolytic virus is a virus that preferentially infects and kills cancer cells. As the infected cancer cells are destroyed by oncolysis, they release new infectious virus particles or virions to help destroy the remaining tumour.

i. Etiology. The type C oncovirus group includes the Moloney murine leukemia and sarcoma viruses, the feline sarcoma and leukemia viruses, gibbon ape leukemia virus, and the guinea pig and bovine type C oncoviruses. Syrian hamster type C virus antigens (SHCVA) were initially observed in human adenovirus-induced hamster tumors (Hatch et al., 1975 ).
Human oncogenic viruses include hepatitis B and hepatitis C viruses (associated with hepatocellular carcinoma (HCC)), Epstein–Barr virus (EBV; associated with B cell lymphomas and nasopharyngeal and gastric carcinomas), HPVs (associated with cervical carcinoma, other anogenital cancers, and a subset of head and neck cancers), human T cell lympho...
