Chronic lymphocytic leukaemia (CLL)

Chronic Lymphocytic Leukaemia (CLL) is a type of blood cancer that occurs when your body makes too many abnormal white blood cells.

CLL is the most common form of leukaemia in adults in Western countries. Approximately 3,709 adults are diagnosed with CLL each year in the UK alone, which is equivalent to 10 new cases every day. Slightly more men than women tend to be affected by CLL and it is often diagnosed in older people, with 59% of diagnoses made in people aged 70 years and over. The disease is rarely, if ever, seen in children.

CLL progresses slowly but, although it can be treated, it is not usually possible to cure chronic leukaemia with standard treatments. Although some CLL patients are treated straight away, some may be ‘actively monitored’ and placed on ‘watch and wait’.
