CCSI is dedicated to providing quality medical oncology, hematology, radiation oncology, and urologic oncology services in central and southern Illinois. Our physicians and staff are caring, compassionate, competent and devoted to giving patients quality care. We encourage patients and their families to actively participate in the patient’s treatment and pain management. In addition, we encourage participation in research studies and clinical trials which often provide treatment options not yet available at other cancer centers, in an investigational setting.
