Hodgkin lymphoma is a type of cancer in the lymphatic system. The lymphatic system is part of the immune system. It helps to fight diseases and infections. The lymphatic system also helps with balancing fluids in different parts of the body. The lymphatic system includes:
- Lymph. This is a fluid that contains lymphocyte cells.
- Lymph vessels. These are tiny tubes that carry lymph fluid throughout the body.
- Lymphocytes. These are a type of white blood cells that fight infections and disease. Burkitt lymphoma grows from B-cells, one type of lymphocyte.
- Lymph nodes. These are small bean-shaped organs. They are in the underarm, groin, neck, chest, abdomen, and other parts of the body. They filter the lymph fluid as it moves around the body.
- Other organs and body tissues. The lymphatic system includes the bone marrow where blood is made. And it includes the spleen, thymus, tonsils, and digestive tract.
Hodgkin lymphoma causes abnormal growth of the cells in the lymphatic system. Over time, the body is less able to fight infection and the lymph nodes swell. Hodgkin lymphoma cells can also spread (metastasize) to other organs and tissues. It’s a rare disease in children. It affects boys more often than girls.
