Chronic Myeloproliferative Neoplasms

Myeloproliferative neoplasms are a group of diseases in which the bone marrow makes too many red blood cells, white blood cells, or platelets. The neoplasms tend to get slowly worse in relation to the increase in extra blood cells.

There are seven types of myeloproliferative neoplasms that are based on whether too many red blood cells, white blood cells, or platelets are being produced. While the body will occasionally make too many of multiple types of blood cells, usually one type is affected more than the others. The types of myeloproliferative neoplasms include:

• chronic myelogenous leukemia;
• polycythemia vera;
• essential thrombocythemia;
• vert and prefibrotic primary myelofibrosis (also called chronic idiopathic myelofibrosis);
• chronic neutrophilic leukemia;
• chronic eosinophilic leukemia; and
• myeloproliferative neoplasms unclassifiable.

Myeloproliferative neoplasms can also sometimes become acute leukemia, in which too many abnormal white blood cells are made.
