A variety of nonmalignant hematologic disorders can evolve into blood malignancies; therefore, close surveillance of nonmalignant hematologic disorders in an oncology/hematology clinic is important for early detection of malignancy. Monoclonal gammopathy of undetermined significance (MGUS) is one nonmalignant, hematologic disorder that is usually aproblematic; however, it can evolve into a blood malignancy such as multiple myeloma or be associated with other chronic conditions.
