What is a CLL?

Chronic Lymphocytic Leukemia (CLL) is a type of cancer that affects the blood and bone marrow, specifically targeting a type of white blood cell called lymphocytes. It is characterized by the accumulation of abnormal lymphocytes, which can interfere with normal blood cell function. CLL typically progresses slowly, and symptoms may include fatigue, swollen lymph nodes, and increased infections. Treatment options vary based on the stage of the disease and may include observation, chemotherapy, or targeted therapies.
