Question: what is the difference between multiple myeloma and waldenstrom's macroglobulinemia?
Answer: Multiple myeloma represents a malignant proliferation of plasma cells derived from a single clone within the bone marrow. While the cause of myeloma is not known, interleukin 6 may play a role in driving myeloma cell proliferation. Waldenstrom's macroglobulinemia (WM) is a proliferative disease of B-lymphocytes.
