Myeloproliferative Neoplasms (MPNs)

Myeloproliferative disorders are a group of rare illnesses that cause blood cells in the bone marrow, including red blood cells, white blood cells, and platelets, to grow and develop abnormally.

Myeloproliferative disorders occur when the body produces too many of one or more types of blood cells. However, the reason for this remains unknown. Researchers believe that genetics and/or the environment may play a role in the development of these disorders.

Myeloproliferative disorders are serious medical conditions. Complications of these disorders may be fatal. A person's survival rate depends on the type of myeloproliferative disorder he/she has, as well as the severity of his/her illness.

Although there is no cure for myeloproliferative disorders, treatment may help patients live several years after they are diagnosed.
