Chronic myelomonocytic leukemia is a disease in which too many myelocytes and monocytes (immature white blood cells) are made in the bone marrow.
In chronic myelomonocytic leukemia (CMML), the body tells too many blood stem cells to become two types of white blood cells called myelocytes and monocytes. Some of these blood stem cells never become mature white blood cells. These immature white blood cells are called blasts. Over time, the myelocytes, monocytes, and blasts crowd out the red blood cells and platelets in the bone marrow. When this happens, infection, anemia, or easy bleeding may occur.
