  schema:description "Myeloma cells are clones of one antibody-making cell, so they pour a single identical antibody, the M-protein, into the blood; measuring it (and the free light chains that go with it) is how myeloma is diagnosed, how deep a response is judged, and how relapse is caught before symptoms."@en ;
