Chronic Myelomonocytic Leukemia

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 develop into 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.

Older age and being male increase the risk of developing chronic myelomonocytic leukemia.

Anything that increases your chance of getting a disease is called a risk factor. Possible risk factors for CMML include the following:

Possible signs of chronic myelomonocytic leukemia include fever, feeling very tired, and weight loss.

These and other symptoms may be caused by CMML. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options for CMML depend on the following:
