Age

Trend over time

Change in chronic lymphocytic leukaemia incidence rates since the early 1990s, UK

 

Chronic lymphocytic leukaemia accounted for 1% of all new cancer cases in the UK in 2017-2019.[1-4]

In females in the UK, chronic lymphocytic leukaemia accounted for less than 1% of all new female cancer cases. In males in the UK, it accounted for 1% of all new male cancer cases).

37% of chronic lymphocytic leukaemia cases in the UK are in females, and 63% are in males.

Chronic lymphocytic leukaemia incidence rates (European age-standardised (AS) rate Open a glossary item) for persons are significantly higher than the UK average in Northern Ireland and significantly lower than the UK average in Scotland and Wales. Rates in England are similar to the UK average.

For chronic lymphocytic leukaemia, there are few established risk factors therefore differences between countries largely reflect differences in diagnosis and data recording.

About this data

Data is for UK, 2017-2019, ICD-10 C91.1.

Last reviewed:

In the UK in 2017-2019, on average each year around 4 in 10 new cases (41%) were in people aged 75 and over.[1-4]

Age-specific incidence rates rise from around age 40-44 more steeply for males than females. Afterwards rates drop in the oldest age group for females and continue rising for males. The highest rates are in the 85 to 89 age group for females and the 90+ age group for males.

Incidence rates are significantly lower for females than males in a number of (mainly older) age groups. The gap is widest at age 30 to 34, when the age-specific incidence rate is 10 times lower for females than males.

Chronic Lymphocytic Leukaemia (C91.1), Average Number of New Cases per Year and Age-Specific Incidence Rates per 100,000 Population, UK, 2017-2019

For chronic lymphocytic leukaemia, like most cancer types, incidence increases with age. This largely reflects cell DNA damage accumulating over time. Damage can result from biological processes or from exposure to risk factors. A drop or plateau in incidence in the oldest age groups often indicates reduced diagnostic activity perhaps due to general ill health.

Chronic lymphocytic leukaemia European age-standardised (AS) Open a glossary item incidence rates for females and males combined increased by 16% in the UK between 1993-1995 and 2017-2019.[1-4] The increase was of a similar size in females and males.

For females, chronic lymphocytic leukaemia AS incidence rates in the UK increased by 14% between 1993-1995 and 2017-2019. For males, chronic lymphocytic leukaemia AS incidence rates in the UK increased by 9% between 1993-1995 and 2017-2019.

Over the last decade in the UK (between 2007-2009 and 2017-2019), chronic lymphocytic leukaemia AS incidence rates for females and males combined decreased by 6%. In females AS incidence rates decreased by 7%, and in males rates decreased by 7%.

Chronic lymphocytic leukaemia incidence rates have increased overall in most broad age groups in females and males combined in the UK since the early 1990s, but have remained stable in some.[1-4] Rates in 0-24s have increased by 595%, in 25-49s have increased by 56%, in 50-59s have increased by 27%, in 60-69s have increased by 23%, in 70-79s have increased by 18% and in 80+s have remained stable.

Chronic Lymphocytic Leukaemia (ICD-10 C91.1), European Age-Standardised Incidence Rates per 100,000 Persons Population, By Age, UK, 1993-2019

For chronic lymphocytic leukaemia there are few established risk factors, therefore increasing incidence in the 1980s and 1990s may largely reflect improvements in diagnosis and data recording.
