It has been reported that some patients have been misdiagnosed with Rare Plasma Cell Leukemia, when in fact the correct diagnosis in their specific case was Multiple Myeloma.
Treatment of multiple myeloma may not be required instantly if there are no symptoms. Treatment may start once the patient starts to experience symptoms. Treatment options involve targeted therapy, immunotherapy, chemotherapy, corticosteroids, radiation therapy and bone marrow transplant. Diagnosis is aided by a blood test to test the M proteins. Urine test as well as imaging tests and bone marrow examination can be helpful as well.
