Evolution and Pathogenesis of Oncoviruses Associated with Head and Neck Cancer: History and Current Concepts

Nearly hundred years back the first oncovirus Rous Sarcoma Virus (RSV) was isolated. From then onwards, researchers have isolated many viruses associated with human cancer. This review summarizes all the oncoviruses in brief and in detail including Human Papilloma Virus (HPV), Epstein-Barr virus (EBV) and Cytomegalo Virus (CMV). This review also discusses about various past and recent patents published in relation to the above mentioned three oncoviruses. Overall this study focuses on the evolution of oncoviruses.
