oncovirus
An oncovirus is a virus that has the potential to cause cancer. These viruses are also referred to as oncogenic viruses or tumor viruses. The mechanism by which oncoviruses cause cancer is complex and can involve several pathways. Some oncoviruses integrate their genetic material into the host cell's DNA, disrupting normal gene regulation and leading to uncontrolled cell growth. Others produce viral proteins that interfere with critical cellular processes, such as DNA repair or programmed cell death (apoptosis), which can accumulate mutations and promote cancer development.
The role of oncoviruses in human cancers has been established for several viral types. For instance, certain
Preventive measures, such as vaccination against HPV and HBV, have proven effective in reducing the incidence
