What is myeloproliferative syndrome?
Myeloproliferative disorders cause blood cells (platelets, white blood cells, and red blood cells) to grow abnormally in the bone marrow. The type of MPD depends on which type of cell your body is overproducing. MPD mostly affects one type of blood cell more than the others, but it sometimes can involve two or more.
What are the classification of myelodysplastic myeloproliferative neoplasms?
