Each antibody (protein) made by the WM cells is the same, so it is called a monoclonal protein, or just an M protein. WM cells make large amounts of a certain type of antibody (immunoglobulin M, or IgM), which is known as a macroglobulin. WM cells have features of both plasma cells and lymphocytes and are called lymphoplasmacytoid. Multiple myeloma is considered a cancer of plasma cells, and non-Hodgkin lymphoma is a cancer of lymphocytes. The cancer cells in people with WM are similar to those of 2 other types of cancer: multiple myeloma and non-Hodgkin lymphoma. T lymphocytes (T cells) help direct immune responses, but they also can kill invading germs directly.Plasma cells make proteins called antibodies (also called immunoglobulins) that help the body attack and kill disease-causing germs like bacteria. B lymphocytes (B cells) respond to an infection by changing into a different type of cell called a plasma cell.Lymphocytes (lymph cells) are the main cells of lymphoid tissue. Throughout body systems like the digestive system and respiratory system.The spleen, an organ on the left side of the abdomen next to the stomach.The thymus, a small organ behind the chest bone and in front of the heart.Bone marrow, the soft inner part of certain bones where new blood cells are made.Lymph nodes, which are pea-sized collections of immune system cells throughout the body, including in the underarm area, in the groin, on the sides of the neck, and inside the chest and abdomen.Lymphoid tissue is found in many places in the body: ![]() ![]() Lymphoid tissue is made up several types of immune system cells that work together to help the body resist infections. To understand WM, it helps to know about the functions of lymphoid tissue in the body. This condition used to be called Waldenstrom’s macroglobulinemia, so some people refer to it as Waldenstrom’s. Another name for WM is lymphoplasmacytic lymphoma. ![]() The cancer cells make large amounts of an abnormal protein (called a macroglobulin). Waldenstrom macroglobulinemia (WM) is a type of non-Hodgkin lymphoma (NHL). ![]()
