comprehensive cancer center
(KOM-pree-HEN-siv KAN-ser ...)
A cancer research center that gets support from the National Cancer Institute (NCI) to do cancer research and provide services directly to cancer patients. Scientists and doctors at these centers do basic laboratory research and clinical trials, and they study the patterns, causes, and control of cancer in groups of people. Also, they take part in multicenter clinical trials, which enroll patients from many parts of the country. Comprehensive Cancer Centers also give cancer information to health care professionals and the public. More information about the NCI Cancer Centers Program can be found on the NCI's Web site at
