Lymphoma

Lymphoma is a type of cancer that starts in the lymphatic system, which is part of the immune system responsible for fighting germs and diseases. It occurs when healthy cells in the lymphatic system grow uncontrollably. The lymphatic system includes lymph nodes (found in the abdomen, groin, chest, underarms, and neck), as well as the spleen, thymus, tonsils, and bone marrow. Lymphoma can affect these areas and other organs. There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma, with over 70 subtypes.
