CLL

Chronic lymphocytic leukemia (CLL) is a type of blood cancer that affects a specific kind of white blood cell called lymphocytes, which are part of the immune system. In CLL, these cells grow abnormally and accumulate over time, often in the blood, bone marrow, and lymph nodes. This can weaken the immune system, making it harder to fight infections. CLL usually progresses slowly and may not cause symptoms early on, but it can eventually lead to fatigue, swollen lymph nodes, and increased infection risk. Treatment options vary based on the stage and symptoms.
