Chronic Myelomonocytic Leukemia (CMML)

Myelodysplastic/myeloproliferative neoplasms (MDS/MPN) are a type of chronic blood cancer in which a person's bone marrow does not make blood effectively. MDS/MPN have both "dysplastic" and "proliferative" features that cannot be classified as either myelodysplastic syndromes (MDS) or myeloproliferative neoplasms (MPN), and for this reason have been categorized as an overlap syndrome with its own distinct characteristics (MDS/MPN).

Chronic myelomonocytic leukemia (CMML) is cancer of the blood, and is considered to be one of the myelodysplastic/myeloproliferative neoplasms.
