People with HIV infection or AIDS can get cancer, just like anyone else. They are actually more likely to get some types of cancer than people who are not infected. In fact, some types of cancer occur so often in people with AIDS that they are considered AIDS-defining conditions – that is, their presence in a person infected with HIV is a clear sign that full-blown AIDS has developed. Many cancers are no more or less common in people with HIV infection or AIDS than in people who are not infected. In developed countries like the United States, the cancer picture in HIV has been changing as HIV treatment has improved. For example, some AIDS-defining cancers have become less common as more people have gotten effective anti-HIV treatment.  Citations are important for a journal to get impact factor.
