In [[hematology]], '''essential thrombocythemia''' ('''ET''') is a rare chronic blood cancer ([[myeloproliferative neoplasm]]) characterised by the [[thrombocythemia|overproduction]] of [[platelets]] (thrombocytes) by [[megakaryocyte]]s in the [[bone marrow]].<ref name="path" /> It may, albeit rarely, develop into [[acute myeloid leukemia]] or [[myelofibrosis]].<ref name="path" /> It is one of the blood cancers wherein the bone marrow produces too many [[White blood cell|white]] or [[red blood cells]], or platelets.<ref name="path">{{cite journal |last1=Beer |first1=PA |last2=Green |first2=AR |title= Pathogenesis and management of essential thrombocythemia|journal=Hematology |volume=2009 |date=2009 |pages=621–628 |doi=10.1182/asheducation-2009.1.621 |pmid=20008247 |doi-access=free }}</ref>
