Leukemia – Chronic Lymphocytic Leukemia (CLL)

Chronic lymphocytic leukemia (CLL) is a type of leukemia in which the body produces too many white blood cells called lymphocytes.


Chronic lymphocytic leukemia (CLL) is a slowly progressing disease in which abnormal lymphocytes crowd out other blood cells, and may collect in the blood, bone marrow, and lymph tissue.

Understanding Your Diagnosis

Your doctor was able to tell that you have leukemia by taking a biopsy. Other tests show the type of leukemia and how far the disease has progressed, called the stage or phase.

Deciding on Treatment

Your treatment choices depend on the results of your lab tests, your health, and your age, as well as the stage of CLL. Your doctor will determine the treatment appropriate for you.

Managing Side Effects

Side effects during cancer treatment vary from person to person. Some people have no side effects, but others may have several. Your health care team will suggest ways to ease any side effects that you experience.

Advanced Reading

Learn more about chronic lymphocytic leukemia from the National Cancer Institute (NCI) Physician Data Query (PDQ®) for patients. It includes information about prevention, screening, and treatment.
