What is Chronic lymphocytic leukemia?
Chronic lymphocytic leukemia (CLL) is the second most common type of leukemia in adults. It often occurs during or after middle age and rarely occurs in children. This type of cancer starts from lymphocytes in the bone marrow and then invades the blood. Usually CLL does not cause any symptoms and is found during a routine blood test. Possible signs include swollen lymph nodes and tiredness. Treatments include bone marrow or peripheral blood stem cell transplantation, monoclonal antibodies, surgery, radiation and chemotherapy.
How do I know if I have Chronic lymphocytic leukemia and what are the symptoms of Chronic lymphocytic leukemia?
Early kidney cancer does not have any symptoms. As the tumor grows larger, people may notice one or more of the following symptoms:
- Weakness and fatigue
- Weight loss for no known reason
- Fever and infection
- Night sweats
- Painless swelling of the lymph nodes in the neck, underarm, or groin.
- Pain or fullness below the ribs.
Other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that the problems can be diagnosed and treated as early as possible.
Who is at risk for chronic lymphocytic leukemia?
Clinical data has suggested that the development of chronic lymphocytic leukemia is related to several factors.
- Certain chemical exposures: Studies suggest that some herbicides and insecticides used in farming may increase the risk of chronic lymphocytic leukemia.
- Family history: Epidemic survey show that first-degree relatives of chronic lymphocytic leukemia patients have an increased risk for this cancer.
- Gender: Clinical data show chronic lymphocytic leukemia is more common in men than women.
- Race: Chronic lymphocytic leukemia is more common in North America and Europe than in Asia.
How to know you have chronic lymphocytic leukemia?
- Blood cell tests: Most chronic lymphocytic leukemia patients have too many of lymphocytes and too few red blood cells and platelets. Besides counting the blood cells, doctors use a number of very precise lab tests, such as cytochemistry, flow cytometry, FISH, immunocytochemistry, cytogenetics, and molecular genetic studies, to diagnose and classify leukemia.
- Bone marrow aspiration and biopsy: The doctor uses a thin needle to draw up a small amount of liquid bone marrow, then a biopsy sample is usually removed and looked at under a microscope.
- Excisional lymph node biopsy: The surgeon cut your lymph node on tne surface of your skin. And, the biopsy sample is usually removed and looked at under a microscope.
- Images tests such as computed tomography (CT) scan, magnetic resonance imaging (MRI), positron emission tomography (PET) scan, ultrasound and chest-x-ray: The goal of these image tests are to help find out the extent of the chronic lymphocytic leukemia and determine the stage of the disease.
When to seek urgent medical care?
Call your health care provider if symptoms of chronic lymphocytic leukemia develop. If you experience either of the following symptoms, seeking urgent medical care as soon as possible:
- Hyperpyrexia
- Severe infection
- Severe abdominal pain

Prevention of chronic lymphocytic leukemia
Chronic lymphocytic leukemia is not related with life style, so there is no known risk factors for people to change. Current data show that avoidance of certain chemical exposures such as herbicides and insecticides may be helpful. But more researches are needed to verify.
What to expect (Outook/Prognosis)?
The prognosis of chronic lymphocytic leukemia depends on:
- The stage of chronic lymphocytic leukemia, whether lymphocytes are spread throughout the bone marrow, whether the chronic lymphocytic leukemia progresses to lymphoma or prolymphocytic leukemia.
- Treatment response: Whether the chronic lymphocytic leukemia patient gets better with treatment or has recurred (come back).
- The patient's general health.
