Myelodysplastic Syndromes (MDS)
MDS, or Myelodysplastic syndromes, are a family of rare disorders in which the bone marrow fails to make enough healthy red blood cells, white blood cells or platelets. This is caused by bone marrow producing lots of underdeveloped, or immature, cells that have an abnormal shape, size or look. These are called blast cells. Most experts agree that MDS is a form of blood and bone marrow cancer.
