Chronic lymphocytic leukemia (CLL) is a type of cancer that begins in the white blood cells of the body's immune system. It is a slow-growing cancer that often has no symptoms, making it difficult to diagnose.
CLL develops when lymphocytes, a type of white blood cell, do not mature and divide properly. As a result, these immature cells accumulate in the blood and lymph nodes, crowding out normal cells. The accumulation of these cells can cause enlarged lymph nodes, spleen, and liver.
CLL can affect people of any age, but it is more common in people between the ages of 65 and 75. There is no one known cause of CLL, but it is believed to be related to genetics and environmental factors.
There is no cure for CLL, but there are treatments available to help manage the disease. Treatment depends on the stage of the disease and the patient's overall health. Treatment options may include chemotherapy, immunotherapy, targeted therapy, and stem cell transplant.
CLL can be a serious and life-threatening disease, but it is often treatable and can be managed with proper care and treatment. It is important that people with CLL get regular check-ups and follow their doctor's advice in order to pursue the best possible outcome.
