myelodysplastic syndrome

(MY-eh-loh-dis-PLAS-tik SIN-drome)

One of a group of cancers in which there are more abnormal cells than normal healthy blood cells (white blood cells, red blood cells, and platelets) in the bone marrow or blood. When there are fewer blood cells, infection, anemia, or bleeding may occur. Sometimes, myelodysplastic syndrome becomes acute myeloid leukemia (AML). Also called MDS.
