Overview
Juvenile myelomonocytic leukemia (JMML) is a serious chronic leukemia (cancer of the blood) that affects children mostly aged 4 and under. The average age of patients at diagnosis is 2 years old. The World Health Organization has included JMML in the category of Myelodysplastic and Myeloproliferative disorders.[1] The name JMML now encompasses all diagnoses formerly referred to as Juvenile Chronic Myeloid Leukemia (JCML), Chronic Myelomonocytic Leukemia of Infancy, and Infantile Monosomy 7 Syndrome.
