The lymphatic system is part of the body's immune defense system. Its job is to help fight diseases and infection. The lymphatic system includes a network of thin tubes that branch, like blood vessels, into tissues throughout the body. Along this network of vessels are small, bean-shaped organs called lymph nodes. Clusters of lymph nodes are found in the underarms, groin, neck, chest and abdomen. Lymphatic tissue is also found in other parts of the body, including the stomach, intestines and skin.
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. When 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.
There are many types of lymphomas. Please use the following links to access comprehensive non-Hodgkin's lymphoma information provided by the National Cancer Institute from its PDQ® Database.
