By altering the function of regulatory genes virus can risk cancer.
Certain infectious agents, such as viruses, bacteria, and parasites, can increase the risk of cancer . In order to reproduce and make more viruses, a virus must enter a living cell and take over the cell's machinery. Some viruses accomplish this by embedding their own DNA (or RNA) into the host cell's. So when DNA or RNA impacts the genes of the host cell, it can cause the cell to become cancerous.
Most viruses only affect specific cells in the body, such as cold virus viruses that affect the nose and throat lining. That is why certain viruses are just associated with specific types of cancer.
