There are two types of rare blood disorders:
Myeloproliferative disorders originate when the bone marrow starts making too many red blood cells, platelets, or certain white blood cells. Together these disorders are referred to as myeloproliferative neoplasms (MPNs).
These diseases tend to worsen as the extra cells build up in the blood or bone marrow and over time may cause bleeding, anemia, infection, or fatigue. MPNs include:
- Polycythemia vera (PCV)
- Essential thrombocythemia
