Main causes of chronic lymphocytic leukaemia
It's not clear what causes chronic lymphocytic leukaemia.
Chronic lymphocytic leukaemia is rare, but it's more common:
- as you get older – it's very rare in people under 40
- if you're male
- if someone in your family has had it
Information:
It's unlikely that your symptoms are caused by cancer, but it's important to get symptoms of chronic lymphocytic leukaemia checked by a GP.
