    • in males, it is the 9th most common cancer (3% of the male total), whilst it is the 11th (2%) in females
    • in 2011, there were 8,616 new cases of leukaemia in the UK: 5,014 (58%) in men and 3,602 (42%) in women, giving a male:female ratio of around 14:10
      • the crude incidence rate shows that there are 16 new leukaemia cases for every 100,000 males in the UK, and 11 for every 100,000 females
      • leukaemia (all subtypes combined) incidence rates have increased overall in Great Britain since the mid-1970s, though much of the rise occurred before the late 1990s
