Chronic lymphocytic leukaemia (CLL)
CLL is a slow-growing (chronic) blood cancer that affects white blood cells in your bone marrow called lymphocytes.
If you’ve got CLL, your body produces too many of a certain type of white blood cell called lymphocytes which don’t work properly. CLL is a chronic condition, which means it usually develops very slowly.
CLL is the most common leukaemia in adults in the UK with around one person in 200 people developing CLL at some point in their life.
