A follicular lymphoma is a type of cancer that affects the lymphatic system. It is a form of non-Hodgkin's lymphoma, which means it is a cancer of the immune system. The disease is characterized by the abnormal growth of B cells in the lymph nodes and other lymphatic organs. These cells are called lymphocytes. Lymphocytes are a type of white blood cell that help fight infections.
