LYMPHOMA is a cancer of a part of the immune system called the lymphatic system. There are many types of lymphoma. One type is called Hodgkin disease. The rest are called non-Hodgkin lymphoma (or NHL), which is what this page will deal with.

NON-HODGKIN LYMPHOMA is cancer of the lymphoid tissue, which includes the lymph nodes, spleen, and other organs of the immune system. There are many different types of non-Hodgkin lymphoma (NHL). It is grouped according to how fast the cancer spreads. The cancer may be growing slowly, moderately, or fast. Burkitt’s lymphoma is an example of a fast-growing lymphoma. Follicular lymphoma is a slow-growing lymphoma.

Most of the time, doctors can’t determine why a person gets non-Hodgkin lymphoma. However, lymphomas may develop in people with weakened immune systems. For example, the risk of lymphoma increases after an organ transplant or in people with HIV infection.
