What is a myeloproliferative neoplasm? MPNs are a group of rare blood cancers that overproduce blood cells in the bone marrow, and are caused by genetic mutations in the blood stem cells:

  • Myelofibrosis is a rare bone marrow cancer. Bone marrow cells that produce blood cells develop and function abnormally resulting in fibrous scar tissue formation.
  • Polycythemia Vera is a disorder in which the bone marrow makes too many red blood cells. It may also result in the production of too many other types of blood cells – white blood cells and platelets.
  • Essential Thrombocythemia causes the body to produce too many blood platelets-thrombocytes. It can cause abnormal clotting or bleeding. The bone marrow makes too many platelet-forming cells or megakaryocytes, which release platelets into your blood.
