Sex differences in cancer incidence among people with HIV infection in the United States

Sex-based cancer disparities among HIV-positive people largely vanished, implicating immune dysfunction over behavior as the primary driver.

In 3.9 million person-years of HIV-cancer registry linkage, sex-based cancer incidence disparities were substantially attenuated for 9 cancer types in HIV+ people, implicating immune dysregulation over behavioral factors as a driver of sex-based cancer risk. These findings challenge assumptions about the biology of sex disparities in cancer.
