What is Hodgkin lymphoma?

Hodgkin lymphoma is cancer that starts in the lymphocytes, the cells of the lymphatic system. The lymphatic system works with your immune system to help your body fight infection and disease. The lymphatic system is made up of a network of lymph vessels (which are a little like veins), lymph nodes and the lymphatic organs (such as the spleen, thymus, tonsils and bone marrow).

Lymph is a clear, yellowish fluid that contains lymphocytes. Lymphocytes are special white blood cells that help fight infection. Lymph nodes are small bean-shaped glands. Clusters of lymph nodes are found in your neck, underarms, chest, abdomen and groin. The lymph nodes filter out waste, bacteria and unwanted cells, including cancer cells, as the lymph passes through them. Lymphatic vessels collect lymph from different tissues throughout the body, filter it through the lymph nodes and return it to the bloodstream.

Hodgkin lymphoma can begin in almost any part of the body. It usually starts in a group of lymph nodes in one part of the body most often the neck and grows in a predictable, orderly way from one lymph node group to the next. Eventually, it can spread to almost any tissue or organ in the body through the lymphatic system or the bloodstream.

Other cancers of the lymphatic system are called non-Hodgkin lymphomas. The cells of Hodgkin lymphoma and non-Hodgkin lymphoma look different, behave differently and are treated differently.
