Juvenile myelomonocytic leukaemia (JMML) is a serious form of chronic leukaemia and accounts for less than 1% of all childhood leukaemias diagnosed.
JMML occurs when too many immature white blood cells, called “myelocytes” and “monocytes,” are made in the bone marrow. They eventually crowd out the healthy, normal cells that belong in the bone marrow.
JMML affects children under the age of six, although most children are diagnosed at closer to two years of age.
The standard course of treatment for JMML is a bone marrow, or stem cell, transplant. Conventional chemotherapy and radiation are not effective treatments.
