Living with Myelodysplastic/myeloproliferative neoplasm

Rare blood and bone marrow diseases that mix features of low and high blood cell production.

Understanding Myelodysplastic/myeloproliferative neoplasm

Myelodysplastic/myeloproliferative neoplasms are rare diseases of the blood and bone marrow.

Normally, the bone marrow makes blood stem cells that grow into mature blood cells. In adults, the two main types are chronic myelomonocytic leukemia (CMML) and atypical chronic myeloid leukemia (CML). A neoplasm that doesn't match these types is called unclassifiable. These neoplasms may progress to acute leukemia.
