Viruses and Bacteria

Being infected with certain viruses or bacteria may increase the risk of developing cancer.

Human papillomaviruses (HPVs): HPV infection is the main cause of cervical cancer and may be a risk factor for other types of cancer. The Federal Drug Administration has approved a vaccine for the prevention of cervical cancer. This vaccine is available in most primary care doctor's offices. Alta Bates Summit Medical Center encourages you to discuss this option with your primary care physician.
Hepatitis B and hepatitis C viruses: Liver cancer can develop after many years of infection with hepatitis B or hepatitis C.
Human T-cell leukemia/lymphoma virus (HTLV-1): Infection with HTLV-1 increases a person's risk of lymphoma and leukemia.
Human immunodeficiency virus (HIV): HIV is the virus that causes AIDS. People who have HIV infection are at greater risk of cancer, such as lymphoma and a rare cancer called Kaposi's sarcoma.
Epstein-Barr virus (EBV): Infection with EBV has been linked to an increased risk of lymphoma.
Human herpesvirus 8 (HHV8): This virus is a risk factor for Kaposi's sarcoma.
Helicobacter pylori: This bacterium can cause stomach ulcers. It also can cause stomach cancer and lymphoma in the stomach lining.

Decrease Your Risk

The Federal Drug Administration has approved a vaccine for the prevention of cervical cancer. Discuss this preventative treatment option with your primary care physician.
Do not have unprotected sex or share needles. You can get an HPV infection by having sex with someone who is infected. You can get hepatitis B, hepatitis C, or HIV infection from having unprotected sex or sharing needles with someone who is infected.
You may want to consider getting the vaccine that prevents hepatitis B infection. Health care workers and others who come into contact with other people's blood should ask their doctor about this vaccine.
If you think you may be at risk for HIV or hepatitis infection, ask your doctor about being tested. These infections may not cause symptoms, but blood tests can show whether the virus is present. If so, the doctor may suggest treatment. Also, the doctor can tell you how to avoid infecting other people.
If you have stomach problems, see a doctor. Infection with H.pylori can be detected and treated.
