Clinical Trials for lymphoma available through KCC and the JCN Lymphoma is a general term for cancers that develop in the lymphatic system . They account for about 4 percent of all cancer cases in the United States. The most common type of lymphoma is called Hodgkin's disease . All other lymphomas are grouped together and are called non-Hodgkin's lymphomas . Like all types of cancer, lymphomas are diseases of the body's cells.
Healthy cells grow, divide and replace themselves in an orderly manner.
This process keeps the body in good repair. In non-Hodgkin's lymphomas, cells in the lymphatic system grow abnormally. They divide too rapidly and grow without any order or control. Too much tissue is formed, and tumors begin to grow. The cancer cells can also spread to other organs.
