Myeloproliferative neoplasms (MPNs) are blood cancers that occur when the body makes too many white or red blood cells in the bone marrow. MPNs were called Myeloproliferative Diseases until 2008 when the World Health Organization reclassified them as cancers and renamed them Myeloproliferative Neoplasms.
There are 4 types of MPNs:
  • Chronic myeloid leukaemia (CML)
  • Polycythemia vera (PV)
  • Essential thrombocythemia (ET)
  • Myelofibrosis (MF)
These conditions are rare and usually develop slowly over a number of years. Most people diagnosed are over 60. Many have other health problems which can make treatment more difficult.
Although myeloproliferative neoplasms can pose health risks, people with these conditions often live for many years after diagnosis. The choice of treatment and how well it works depends largely on the type of MPNs.
If you have any problems, please consult your doctor.
