Chronic Myeloid Leukemia (CML)

Condition Basics

What is chronic myeloid leukemia (CML)?

Chronic myeloid leukemia (CML) is type of cancer in which the bone marrow makes too many white blood cells. In CML, young white blood cells grow abnormally, and they don't mature or die off as they should. These abnormal cells can crowd out normal blood cells and cause problems.

CML usually gets worse slowly. But sometimes it changes into a fast-growing acute leukemia. This is called a blast crisis.

What causes it?

Experts don't know what causes leukemia in most people. But they think that most leukemia happens because of things in the environment and in a person's genes.

Some things may increase the risk, such as having certain genetic conditions or being exposed to large amounts of radiation or certain chemicals.

What are the symptoms?

CML often doesn't cause symptoms. When it does, they may include tiredness (fatigue), a feeling of fullness below the ribs, fever, weight loss, and loss of appetite. If the disease gets worse, it may lead to infections, easy bruising or bleeding, and belly or bone pain.

How is it diagnosed?

Your doctor will ask about your past health and any symptoms you've had. You'll have a physical exam and blood tests. You'll most likely have a bone marrow aspiration and biopsy. The doctor may do more tests to learn about the type of leukemia and how severe it is.

How is CML treated?

Targeted therapy, Opens dialog with a tyrosine kinase inhibitor is usually the first treatment for CML. In some cases, a stem cell transplant, Opens dialog may be needed. Treatments for CML may include chemotherapy and other medicines, including corticosteroids. A clinical trial may also be a good option.
