What is chronic lymphocytic leukemia?


Chronic lymphocytic leukemia (CLL) starts from lymphocytes, a type of white blood cells, in the bone marrow. It will then spread to the blood quickly. The disease mostly targets older adults.

Unlike the acute one, in CLL, it takes time for leukemia cells to build up so that many patients don’t notice it for a few years at minimum, because they don’t related symptoms. As CLL develops, it can further spread to other parts of the body, such as the lymph nodes and spleen.

Symptoms of CLL may include fatigue, fever, unexplained weight loss, swelling lymph nodes without pain and enlargement of the spleen and anemia.
