Chronic lymphocytic leukaemia

In chronic lymphocytic leukaemia (CLL), lymphocytes don’t grow properly in your bone marrow and also live too long! Instead of growing out of control, like in acute types of leukaemia, in CLL the faulty cells grow at a normal rate, but live longer than cells should do, so they build up this way! CLL develops very slowly, over months or years. It’s the most common type of leukaemia, but it's usually people who are over 60 years old who get it.
