Myeloproliferative neoplasms (MPNs) are a group of blood cancers that occur when the body creates too many white blood cells, red blood cells, or platelets. “Myelo-” locates the problem in the bone marrow, the part of the body where blood cells are made. “Proliferative” means that certain cells in the bone marrow are reproducing and spreading quickly. Finally, “neoplasms” are cells that grow abnormally.
MPNs are broken down into three main subcategories: essential thrombocythemia (ET), myelofibrosis (MF), and polycythemia vera (PV). MPNs are highly treatable and there are expanding treatment options available as well as clinical trial options that aim to improve further on the current successes.
