Editorial: The role of DNA viruses in human cancers

There is a wide variety of human tumor viruses, including small DNA viruses such as Merkel cell 8 polyomavirus (MCPyV), hepatitis B virus (HBV) and human papillomaviruses (HPV), or large DNA 9 viruses as Kaposi's sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV) (Chen et 10 al., 2021). Around 85% of virus-induced cancers occur in developing countries, which has important 11 implications for the translation of knowledge into public health treatment. As well, certain viruses are 12 likely to contribute to sex-specific differences in tumorigenesis. Almost 90% of HPV-induced cancers 13are almost exclusively diagnosed in women, whereas HBV, HCV and EBV cancers are generally 14 diagnosed in men (Plummer et al., 2016
