viral oncogenesis

Viral oncogenesis refers to the process where certain viruses can cause cancer in humans. Some viruses insert their genetic material into our cells' DNA, disrupting normal cell functions and controlling mechanisms that prevent unchecked growth. This integration can lead to the formation of tumors over time. Examples include human papillomavirus (HPV) linked to cervical cancer, hepatitis B and C viruses associated with liver cancer, and Epstein-Barr virus connected to certain lymphomas. Not everyone infected develops cancer; other factors like genetics and environment also play roles. Understanding viral oncogenesis helps in prevention, vaccination, and targeted treatments.
