Infection with HIV, the virus that causes acquired immune deficiency syndrome
(AIDS), does not seem to be a direct cause of cancers. But because HIV infection
weakens the body’s immune system, it increases a person’s risk of getting several
types of cancer, especially some linked to other viruses. HIV is spread through
semen, vaginal fluids, blood, and breast milk from an HIV-infected person. HIV is
not spread by insects, through water, or by casual contacts such as talking, shaking
hands, hugging, coughing, sneezing, or from sharing dishes, bathrooms, kitchens,
phones, or computers.
Known routes of HIV spread include:

• Unprotected sex (oral-least likely, vaginal, or anal-most likely) with an
HIV-infected person
• Injections with needles or injection equipment previously used by an
HIV-infected person
• Prenatal and perinatal (during birth) exposure of infants from mothers
with HIV
• Breastfeeding by mothers with HIV
• Transfusion of blood products containing HIV (U.S. blood has been tested
since 1985)
• Organ transplants from an HIV-infected person (donors are now tested for
• Penetrating injuries or accidents (usually needle sticks) in health care workers

HIV infects, weakens and destroys the immune system’s helper T-cells and increases
susceptibility to cancer. This leaves the body susceptible to the damage caused
by other viruses such as HPV, and a weak immune system may not attack and destroy
newly formed cancer cells. HIV infection has been linked to a higher risk of
developing anal cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, lung cancer,
cancers of the mouth and throat, skin cancers (basal cell, squamous cell, and Merkel
cell), Kaposi sarcoma, invasive cervical cancer, and central nervous system lymphoma.
Taking anti-HIV drugs may reduce the risk of getting these cancers.

Less common cancers that are linked to viral infection
Epstein-Barr virus (EBV) is a herpes virus that infects almost everyone in the U.S.
before the age of 20. EBV causes the symptoms of infectious mononucleosis in
some people. EBV remains in the body throughout life and increases a person’s
risk of getting rare cancers, including nasopharyngeal cancer and fast-growing lymphomas
such as Burkitt lymphoma. Other rare cancers that are linked to viral infections,
especially in people with weak immune systems, include Kaposi sarcoma,
primary effusion lymphoma, multicentric Castleman disease, adult T-cell leukemia/
lymphoma (ATL) and Merkel cell skin cancer.
