Question: what is aplastic anemia and other myelodysplastic syndromes?
Answer: Aplastic anemia and myelodysplastic syndromes (MDS) are rare and serious disorders that affect the bone marrow and blood. Bone marrow is the soft, spongelike tissue inside the bones. Bone marrow makes stem cells that develop into one of the three types of blood cells—red blood cells, white blood cells, or platelets.
