Lymphoma is a type of blood cancer that starts in the immune system cells which are called lymphocytes or better known as white blood cells. These cells move throughout the body in a fluid called lymph and work to protect the whole body from infection. Lymphoma occurs when lymphocytes transform and start to multiply uncontrollably where then the abnormal lymphocytes collect in the lymph nodes and form a mass of cells, a tumor. The different types of Lymphoma include: Chronic lymphocytic leukemia, Cutaneous B-cell lymphoma, Cutaneous T-cell lymphoma, Hodgkin’s lymphoma, non-Hodgkin’s lymphoma, and Waldenstrom macroglobulinemia.
