Myeloproliferative neoplasms
Myeloproliferative neoplasms (MPNs) are a group of blood diseases where the
MPNs are classified as blood cancers because the blood cells are being made in an uncontrolled way. But MPNs often develop and progress slowly (called chronic) so they need only mild treatments.
The main types of MPNs are:
- polycythemia vera
- essential thrombocythemia
- myelofibrosis
Chronic myeloid leukemia (CML) is the most common type of leukemia and is also considered an MPN. Find out more about chronic myeloid leukemia (CML).
There are rare types of MPNs that do not have a standard treatment, such as chronic neutrophilic leukemia and chronic eosinophilic leukemia.
There are some MPNs that also have features of myelodysplastic syndromes (MDSs). These are called myelodysplastic/myeloproliferative neoplasms. They include chronic myelomonocytic leukemia (CMML) and atypical chronic myeloid leukemia (aCML).
