Lymphoma is a type of blood cancer that occurs when lymphocytes, which are white blood cells that help protect the body from infection and disease, begin behaving abnormally. Abnormal behaviour in lymphocytes means that they may divide and replicate faster than normal cells or that they do not die off when they are supposed to.
Lymphoma may develop in many parts of the body, including the lymph nodes, spleen, bone marrow, blood or other organs.
