Cancer arises when any given body cell starts to divide in places and at times at which this is not desirable. The abnormal cell grows out of control and has a selective advantage over its neighbors, thereby forming a tumor. The aberrant growth in most tissues results in the formation of a solid tumor. However, tumors originating in blood, bone marrow and the lymphatic system, such as leukemia, multiple myeloma and lymphoma, don’t have a centralized location and are called ‘liquid’ tumors. Multiple myeloma is also called Kahlers disease and is the result of an abnormal growth of a specific type of bone marrow cells, the so-called plasmocytes. Plasmocytes are the antibody-producing cells of the immune system.
