現在最成功的抗癌方案都是利用自身的免疫機製. 如果人的免疫力降低，比如感染艾滋病，是否會增加患癌的風險呢？

Yes. People infected with HIV have a substantially higher risk of some types of cancer compared with uninfected people of the same age (1). The general term for these cancers is "HIV-associated cancers." Three of these cancers are known as "acquired immunodeficiency syndrome (AIDs)-defining cancers" or "AIDS-defining malignancies": Kaposi sarcoma, aggressive B-cell non-Hodgkin lymphoma, and cervical cancer. A diagnosis of any of these cancers in someone infected with HIV confirms a diagnosis of AIDS.

Compared with the general population, people infected with HIV are currently about 500 times more likely to be diagnosed with Kaposi sarcoma, 12 times more likely to be diagnosed with non-Hodgkin lymphoma, and, among women, 3 times more likely to be diagnosed with cervical cancer (2).

In addition, people infected with HIV are at higher risk of several other types of cancer (collectively called "non–AIDS-defining cancers") (1, 2). These other malignancies include cancers of the anus, liver, oral cavity/pharynx, and lung, and Hodgkin lymphoma (3, 4).

People infected with HIV are 19 times more likely to be diagnosed with anal cancer, 3 times as likely to be diagnosed with liver cancer, 2 times as likely to be diagnosed with lung cancer, about 2 times as likely to be diagnosed with oral cavity/pharynx cancer, and about 8 times more likely to be diagnosed with Hodgkin lymphoma compared with the general population (2).

In addition to being linked to an increased risk of cancer, HIV infection is associated with an increased risk of dying from cancer. HIV-infected people with a range of cancer types are more likely to die of their cancer than HIV-uninfected people with these cancers (5, 6).
