September has been designated “blood cancer awareness month” by the Leukemia and Lymphoma Society. Blood cancers rarely produce signs or symptoms until they are very advanced. They are typically discovered by doctors performing routine blood work for other reasons or because of swelling of the lymph nodes.
Myeloproliferative neoplasms (MPN) are a related group of blood cancers. In these disorders, the bone marrow cells that produce blood cells develop and function abnormally. The three main types of MPN are polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). In addition to developing on its own, myelofibrosis may also develop as a result of ET or PMF.
As the month of September brings blood cancers into focus, CancerConnect is committed to increasing public understanding of Myeloproliferative Neoplasms and providing access to breaking treatment news and resources as well as dedicated social communities where individuals impacted by PV, ET, and MF can share information, support and inspiration throughout the year.
