IMPORTANCEIn combination with a decreased risk of AIDS-defining cancers and improved survival of people infected with HIV, the burden of non-AIDS-defining cancer has increased markedly.Although a substantial number of studies have measured the cancer risk among people with HIV in developed countries, little research has been conducted on the risk of cancer in HIV-infected people in Asia. OBJECTIVE To examine the cancer incidence and the estimated risk of cancer among people in Korea infected with HIV compared with the general population.
