Yes. Antiretroviral (ARV) treatments prevent about two thirds of the cancers in HIV-infected people, particularly Kaposi sarcoma and one type of lymph-node cancer (non-Hodgkin lymphoma). For some cancers, the beneficial effect of ARV treatments is less obvious, such as for cancers of the cervix, anus, and lung, or another type of cancer of the lymph nodes (Hodgkin lymphoma). Not surprisingly, a result of improved survival rates is that people with HIV now live to older ages, when cancers are generally more frequent even in people who are not HIV-infected. Cancer screening is therefore also very important in people with HIV.
