Chronic myeloproliferative disorders

What are chronic myeloproliferative disorders?
Chronic myeloproliferative disorders are a group of slow-growing cancers in which too many blood cells (red blood cells, white blood cells or platelets) are produced by the bone marrow. The extra blood cells inhibit the rest of the blood cells in functioning properly. Chronic myeloproliferative disorder can sometimes become acute leukemia when too many abnormal white blood cells are produced.

There are six types of myeloproliferative disorders:
• Chronic myelogenous leukemia
• Polycythemia vera
• Primary myelobrosis
• Essential thrombocythemia
