Human immunodeficiency virus (HIV) HIV, the virus that causes acquired immune deficiency syndrome (AIDS), doesn’t appear to cause cancers directly. But HIV infection increases a person’s risk of getting several types of cancer, especially some linked to other viruses.
Can influenza virus cause cancer?
Some viruses can cause or contribute to the development of cancer. These viruses are called oncogenic viruses. Unlike other viruses, such as influenza viruses, that cause an acute infection, oncogenic viruses often cause long-term, persistent infections.

Bacterial infections traditionally have not been considered major causes of cancer. Recently, however, bacteria have been linked to cancer by two mechanisms: induction of chronic inflammation and production of carcinogenic bacterial metabolites.
What is the difference between virus and cancer?
Changes or mutations in cellular DNA have the potential to turn normal healthy cells into cancer cells. Viruses may also cause inflammation, a known risk factor for some cancers. But most viruses do not lead to cancer, and most cancers are not caused by viruses.
