Plasmapheresis can be particularly beneficial in treating certain cancers and their related conditions. For example, it is often used to manage multiple myeloma, a cancer of plasma cells, and Waldenstrom’s macroglobulinemia, a type of non-Hodgkin lymphoma. These cancers can cause high levels of abnormal proteins in the blood, which plasmapheresis helps to remove, thereby reducing symptoms and improving quality of life.
