How do viruses cause cancer?
When viruses cause an infection, they spread their DNA, affecting healthy cells’ genetic makeup and potentially causing them to turn into cancer. HPV infections, for instance, cause the virus’ DNA to combine with the host’s DNA, disrupting the normal function of cells.
Can a virus produce cancer?
Researchers know that there are several viruses that can lead to cancer. For example, the human papillomavirus (HPV) can cause cervical and several other cancers. And hepatitis C can lead to liver cancer and non-Hodgkin’s lymphoma.
What are 4 general ways viruses can cause cancer?
How a Virus Causes Cancer
- Directly damage DNA in host cells, resulting in cancer.
- Altering the immune system so that it is less able to fight off cancer cells (which could have initially developed due to something other than the virus)
- Chronic inflammation.
- Disrupting the body’s normal regulation of cell division.
How do viruses cause disease?

Which virus does not cause cancer?
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.
Do RNA viruses cause cancer?
Both DNA and RNA viruses have been shown to be capable of causing cancer in humans. Epstein-Barr virus, human papilloma virus, hepatitis B virus, and human herpes virus-8 are the four DNA viruses that are capable of causing the development of human cancers.
