Types of Myeloproliferative Neoplasms (MPNs)
There are four major types of myeloproliferative disorders:
Chronic myelogenous leukemia
A chronic form of cancer that starts in the blood-forming cells of the bone marrow and invades the blood and other parts of the body over time.
Essential thrombocythemia (ET)
A type of leukemia in which bone marrow produces too many platelets, increasing the risk of blood clots which can lead to strokes and heart attacks.
Also called agnogenic myeloid metaplasia (AMM), a form of cancer that arises in the bone marrow.
A rare blood disorder in which there is an increase in all blood cells, particularly red blood cells.
