The National Cancer Institute is conducting the HIV/AIDS Cancer Match Study to examine cancer risk in people living with HIV infection. The study utilizes data collected by state HIV and cancer registries throughout the United States.

virus with peoplePeople who are infected with the human immunodeficiency virus (HIV) or who have the acquired immunodeficiency syndrome (AIDS) have an elevated risk for some cancers. This high risk occurs because HIV weakens the immune system, and because many other cancer risk factors are common in HIV-infected people.

By studying the patterns of cancer risk among HIV-infected people, NCI investigators seek to better understand how the immune system protects people from developing cancer. Another goal of the study is to look for trends in cancer risk in the HIV populations and identify important opportunities for cancer prevention.

The study does not recruit participants, because it uses only data previously collected by public health agencies.
