Bowel cancer mortality statistics

Mortality statistics for bowel cancer by country in the UK, age and trends over time are presented here. There are also data by geography and socio-economic variation. Unless otherwise stated the ICD codes for bowel cancer (sometimes called colorectal cancer) are ICD-10 C18-C20 (which include cancers of the colon, rectum and rectosigmoid junction).

The latest mortality statistics available for bowel cancer in the UK are 2011. Find out why these are the latest statistics available.

By country in the UK

Bowel cancer is the second most common cause of cancer death in the UK (2011), accounting for around 10% of all cancer deaths. Bowel cancer is the third most common cause of cancer death among men in the UK (2011), accounting for 10% of all male deaths from cancer.1-3 Among women in the UK, bowel cancer is also the third most common cause of cancer death (2011), responsible for 9% of all female cancer deaths.

In 2011, there were 15,659 deaths from bowel cancer in the UK (Table 2.1): 8,520 (54%) in men and 7,139 (46%) in women, giving a male:female ratio of 12:10.1-3 The crude mortality rate shows that there are 27 bowel cancer deaths for every 100,000 males in the UK and 22 for every 100,000 females.

Around 6 out of 10 (62%) of all bowel cancer deaths are due to cancers of the colon (9,723) and over one-third (38%) are deaths from rectal cancer (5,936). More rectal cancer deaths occur in men (2,369 or 64% males), while colon cancer deaths are similar between men and women (4,980 or 51% male).

The European age-standardised mortality rates (AS rates) are significantly lower in England and Wales compared with Scotland.1-3 Rates do not differ significantly between the other constituent countries of the UK for either sex.

A north-south divide in bowel cancer mortality rates has existed across the UK since at least the 1990s4 and the latest analysis of bowel cancer mortality rates throughout the UK reports significant variation for males, with the highest rates being in the North of England and the lowest rates being in parts of London and the South.5,6

By age

Bowel cancer mortality is strongly related to age, with the highest mortality rates being in older men and women. In the UK between 2009 and 2011, an average of 57% of bowel cancer deaths were in men and women, aged 75 years and over (Figure 2.1).1-3  

Age-specific mortality rates increase sharply from around age 50 in men and around age 65 in women, with the highest rates in the 85+ age group in both sexes. Mortality rates are higher for males than for females in adults aged 45 and over and this gap is widest between the ages of 60 and 74, when the male:female mortality ratio of age-specific mortality rates (to account for the different proportions of males to females in each age group) is around 18:10 (Figure 2.1).1-3

Almost a fifth (19%) of bowel cancer deaths occur in people aged 60-69. People in England and Northern Ireland are currently offered bowel screening at two-year intervals between ages 60 and 69. In Scotland people are offered screening from ages 50 to 74. In Wales people are offered screening from ages 60 to 74. In England screening is gradually being extended to include people aged 70-74.

Trends over time

Bowel cancer mortality rates have decreased overall in the UK since the early 1970s (Figure 2.2).1-3 For males, European AS mortality rates decreased by 38% between 1971-1973 and 2009-2011. The decline is bigger for females, with rates decreasing by 51% between 1971-1973 and 2009-2011.

Over the last decade (between 2000-2002 and 2009-2011), the European AS mortality rates have decreased by 15% in males and 13% in females respectively. There are likely to be several reasons for the decline, including earlier detection and better treatment.

Bowel cancer mortality rates have decreased overall for all of the broad age groups in the UK since the early 1970s (Figure 2.3).1-3 The largest decreases have been in people aged between 35 and 44, with European AS mortality rates decreasing by 63% between 1971-1973 and 2009-2011. Lower mortality decreases in age groups over 60 may be explained in part by the under-staging and under-treatment of the elderly.5 The impact of screening on mortality rates in different age groups should be seen in the data in the coming years.

The impact of nationwide bowel screening programmes on mortality rates should also be seen in the data in the coming years. Bowel screening pilot studies conducted from 2000 onwards in the West Midlands and Scotland have shown that the risk of dying from bowel cancer is reduced by around a quarter in people who are screened.11-13 Bowel screening started in England for 60-69 year olds in 2006 and has since been introduced across the UK, although the age groups being offered screening differs between countries.

In Europe and worldwide

Bowel cancer (C18-C21) is the second most common cause of cancer death in Europe, with around 215,000 deaths from bowel cancer in 2012 (12% of the total). In Europe (2012), the highest World age-standardised mortality rates for bowel cancer are in Hungary for both men and women; the lowest rates are in Albania for both men and women. UK bowel cancer mortality rates are estimated to be the 10th lowest in males in Europe, and 14th lowest in females.20 These data are broadly in line with Europe-specific data available elsewhere.21

Bowel cancer (C18-C21) is the 4th most common cause of cancer death worldwide, with around 694,000 deaths from bowel cancer in 2012 (8% of the total). Bowel cancer mortality rates are highest in Central and Eastern Europe and lowest in Western Africa, but this partly reflects varying data quality worldwide.20

By socio-economic variation

There is evidence for an association between bowel cancer mortality and deprivation for males and females in England (although the association is small for females).16 England-wide data for 2007-2011 show European age-standardised mortality rates are 30% higher for males living in the most deprived areas compared with the least deprived, and 15% higher for females (Figure 2.6). Male differences in deprivation are more marked than for females.16

The estimated gap in bowel cancer mortality between people living in the most and least deprived areas in England has not changed in the period 2002-2011. It has been estimated that there would have been around 860 fewer bowel cancer deaths each year in England during 2007-2011 if all people experienced the same mortality rates as the least deprived.16

Associations with deprivation have also been investigated for incidence.
