Chronic Lymphocytic Leukemia (CLL)

Condition Basics

What is chronic lymphocytic leukemia (CLL)?

Chronic lymphocytic leukemia (CLL) is a cancer of the blood cells. It's a type of leukemia in which the bone marrow makes too many young white blood cells called lymphocytes.

In CLL, some of these lymphocytes grow abnormally and don't mature or die off as they should. Instead, they become leukemia cells. These leukemia cells slowly crowd out normal blood cells in the blood, bone marrow, lymph nodes, and spleen.

CLL is also called chronic lymphoblastic leukemia. It usually gets worse slowly.

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?

CLL often doesn't cause any symptoms. When it does, they may include swollen lymph nodes; fatigue; a feeling of fullness below the ribs; weight loss for no clear reason; and fever, chills, and night sweats. If it gets worse, it may cause anemia, infections, and easy bruising or bleeding.

How is it diagnosed?

Your doctor will ask about your past health and do a physical exam. You'll have blood tests. If the results point to leukemia, the doctor may do other tests to learn more about the disease. For example, you'll have genetic tests. You may have imaging tests or a bone marrow biopsy.

How is CLL treated?

Treatments for CLL include targeted therapy, Opens dialog, chemotherapy, Opens dialog and immunotherapy, Opens dialog (chemoimmunotherapy), and stem cell transplants, Opens dialog. But treatment isn't always needed right away. And if you don't respond to treatment, or if the leukemia comes back, your doctor will discuss your options for more treatment. Or your doctor may recommend that you join a clinical trial.
