Chronic lymphocytic leukemia (CLL) is a type of blood cancer that affects a specific kind of white blood cell called a lymphocyte. Lymphocytes are an essential part of your body's immune system, helping to fight infections. In people with CLL, the body produces an abnormally high number of lymphocytes that don't function properly.
In most cases, the exact cause of CLL is unknown. However, certain factors may increase your risk of developing this condition, including:
Having a family history of CLL (parent, sibling, or child)
Being middle-aged or older
Being a white male
Having relatives who are Eastern European or Russian Jews
Exposure to Agent Orange, an herbicide used during the Vietnam War
In the early stages, CLL may not cause any noticeable symptoms. As the disease progresses, you may experience:
Swollen lymph nodes in your neck, armpits, stomach, or groin
Shortness of breath
Pain or fullness in your stomach due to an enlarged spleen
Fatigue
Night sweats
Fever and frequent infections
Loss of appetite and weight
If your doctor suspects you may have CLL, they will likely order a blood test to check the levels of lymphocytes, platelets, and red and white blood cells in your blood. If the white blood cell count is high, your doctor may recommend a bone marrow aspiration and biopsy to confirm the diagnosis and determine the stage of the disease.
The treatment plan for CLL depends on the stage of the disease and the presence of symptoms. In some cases, early-stage CLL may not require immediate treatment and can be monitored closely by your doctor. When treatment is necessary, options may include:
Chemotherapy drugs are used to kill or control cancer cells. These medications can be administered orally, by injection, or through an IV. Common side effects include mouth sores, nausea, and low blood counts.
Immunotherapy drugs help your body's immune system recognize and destroy cancer cells. Monoclonal antibodies, a type of immunotherapy, are often used to treat CLL. Side effects may include headache, fever, rash, and blood pressure changes.
Targeted therapy drugs block specific proteins in and on cancer cells that help them survive and spread. These medications are taken as pills and may cause side effects such as low blood counts, diarrhea, nausea, fatigue, and skin rashes.
In some cases, radiation therapy, surgery, or leukapheresis may be used to address specific symptoms or complications of CLL. Clinical trials and stem cell transplants are also being studied as potential treatment options for certain patients.
Living with CLL can be challenging, but there are ways to manage the physical and emotional aspects of the disease. Some tips include:
Communicating openly with your healthcare team about any side effects or concerns
Staying active and engaging in gentle exercises like walking or yoga
Practicing stress-reducing techniques such as meditation or deep breathing
Setting small, achievable goals on days when your energy and mood are low
Seeking support from friends, family, or support groups
Organizations like the Leukemia & Lymphoma Society offer resources and support for people living with CLL, including educational programs, support groups, online chats, and one-on-one support from someone who has been through a similar experience.
