Kaposi's sarcoma is a cancer that can form masses in the skin and is caused by the Kaposi's sarcoma-associated herpesvirus (KSHV), also called HHV-8. DNA viruses * Human papillomavirus (HPV), a DNA virus, causes transformation in cells through interfering with tumor suppressor proteins such as p53. Interfering with the action of p53 allows a cell infected with the virus to move into a different stage of the cell cycle, enabling the virus genome to be replicated. Forcing the cell into the S phase of the cell cycle could cause the cell to become transformed. Human papillomavirus infection is a major cause of cervical cancer, vulvar cancer, vaginal cancer, penis cancer, anal cancer, and HPV-positive oropharyngeal cancers. There are nearly 200 distinct human papillomaviruses (HPVs), and many HPV types are carcinogenic. *Hepatitis B virus (HBV) is associated with Hepatocarcinoma * Epstein–Barr virus (EBV or HHV-4) is associated with four types of cancers * Human cytomegalovirus (CMV or HHV-5) is associated with mucoepidermoid carcinoma and possibly other malignancies. *Kaposi's sarcoma-associated herpesvirus (KSHV or HHV-8) is associated with Kaposi's sarcoma, a type of skin cancer. *Merkel cell polyomavirusa polyoma virusis associated with the development of Merkel cell carcinoma RNA viruses Not all<unk> es are DNA viruses. Some RNA viruses have also been associated such as the hepatitis C virus as well as certain retroviruses, e.g., human T-lymphotropic virus (HTLV-1) and Rous sarcoma virus (RSV). Overview table Virus Percent of cancers Associated cancer types Hepatitis B virus (HBV) Hepatocarcinoma Hepatitis C virus (HCV) HCV is a known carcinogen, causing hepatocarcinoma Human T-lymphotropic virus (HTLV) 0.03 Adult T-cell leukemia Human papillomaviruses (HPV) 5.2 HPV types 16 and 18 are associated with cancers of cervix, anus, penis, vulva, vagina, and HPV-positive oropharyngeal cancers. According to statistics in the United States, females are more impacted by HPV-associated cancers (83%) than males (74%).
