Smouldering myeloma

Smouldering myeloma, also known as smoldering myeloma, indolent myeloma or asymptomatic myeloma, is a very slow-growing type of myeloma which is characterised by a proliferation of malignant plasma cells and a subsequent overabundance of monoclonal paraprotein (M protein). Smouldering myeloma is a very early phase of myeloma and is devoid of symptoms but a bone marrow biopsy shows definite evidence of myeloma.
