There's good news and bad news for HIVers when it comes to non-Hodgkin's lymphoma, one of three AIDS-defining cancers. The upside is that successful antiretroviral therapy slashes risks for the disease by half. But the bad news, according to a study of nearly 8,500 people who developed the cancer, is that HIVers -- even those successfully treated with antiretroviral drugs -- are twice as likely to die within two years of their lymphoma diagnosis than are HIV-negative adults.
