Several types of infections are linked to cancer. Among the most notable are: - [Human Papillomavirus (HPV)](): Linked to cervical, anal, and oropharyngeal cancers. - [Hepatitis B and C Viruses (HBV and HCV)](): Associated with liver cancer. - [Epstein-Barr Virus (EBV)](): Linked to nasopharyngeal cancer and some types of lymphoma. - [Helicobacter pylori (H. pylori)](): Associated with gastric cancer. - [Human Immunodeficiency Virus (HIV)](): While not directly causing cancer, HIV weakens the immune system, making it easier for cancers like Kaposi’s sarcoma and non-Hodgkin lymphoma to develop.
