Clinical trials test new treatments for diseases, including AIDS-related lymphoma, that researchers think may be more effective than the usual treatment. If you volunteer for a clinical trial, you may get either the usual treatment or the new treatment.
A clinical trial may provide cutting-edge treatment, but not everyone will qualify. For example, some clinical trials want only people who have never had any sort of treatment for their AIDS-related lymphoma, or they may want people with cancer that has not responded to the usual treatment. You can ask your doctor whether a clinical trial may be right for you.
