Myeloproliferative disorders, also called myeloproliferative neoplasms, are caused by the overproduction of red blood cells, white blood cells, and/or platelets in the bone marrow. They increase your risk for stroke, blood clots, and heart attack and may cause an enlarged spleen. Common types include:
- Polycythemia vera -- too many red blood cells
- Essential thrombocytosis -- too many platelets, the blood cells that help the blood clot
- Myelofibrosis -- excessive collagen or fibrous tissue in the bone marrow that interferes with blood cell production
- Chronic myelogenous leukemia (CML) -- an increased production of white blood cells in the bone marrow
These diseases have similar criteria for diagnosis, which is why it’s important for one of our experienced specialists to evaluate your condition.
