Change in small intestine cancer incidence rates since the early 1990s, UK

Small intestine cancer is not among the 20 most common cancers in the UK, accounting for less than 1% of all new cancer cases (2017-2019).[1-4]

In females in the UK, small intestine cancer is not among the 20 most common cancers (less than 1% of all new female cancer cases). In males in the UK, it is not among the 20 most common cancers (less than 1% of all new male cancer cases).

45% of small intestine cancer cases in the UK are in females, and 55% are in males.

Small intestine cancer incidence rates (European age-standardised (AS) rate Open a glossary item) for persons are similar to the UK average in all the UK constituent countries.

About this data

Data is for UK, 2017-2019, ICD-10 C17.

Last reviewed:

In the UK in 2017-2019, on average each year around a third of new cases (34%) were in people aged 75 and over.[1-4]

Age-specific incidence rates rise steadily from around age 30-34 and more steeply from age 45-49 and drop in the oldest age groups. The highest rates are in the 85 to 89 age group for females and the 80 to 84 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 90+, when the age-specific incidence rate is 1.9 times lower for females than males.

Small Intestine Cancer (C17), Average Number of New Cases per Year and Age-Specific Incidence Rates per 100,000 Population, UK, 2017-2019

For small intestine cancer, 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.

The most common specific location for small intestine cancers in the UK is the duodenum (2016-2018).[1-4] Variation of incidence by anatomical site may reflect the physical size of each site, and differences in risk factor exposure by site, among other factors.

The number of new small intestine cancer cases on average each year in the UK is projected to rise from around 2,600 cases in 2023-2025 to around 4,500 cases in 2038-2040.[1]

Small intestine cancer incidence rates are projected to rise by 44% in the UK between 2023-2025 and 2038-2040, to 6 cases per 100,000 people on average each year by 2038-2040.[1] This includes a similar increase for males and females.

For females, small intestine cancer European age standardised (AS) Open a glossary item incidence rates in the UK are projected to rise by 52% between 2023-2025 and 2038-2040, to 5 cases per 100,000 per year by 2038-2040.[1] For males, AS rates are projected to rise by 37% between 2023-2025 and 2038-2040, to 6 cases per 100,000 per year by 2038-2040.[1]

Calculated by the Cancer Intelligence Team at Cancer Research UK, February 2023. Age-period-cohort modelling approach described here, using 2020-based population projections (Office for National Statistics) and observed cancer incidence (1975-2018 for England, Scotland and Wales, 1993-2018 for Northern Ireland).

About this data

Projections are based on incidence data from 1975-2018 (England, Scotland and Wales) and 1993-2018 (Northern Ireland); the above figure presents all UK data from 1993-2018 (observed) and 2019-2040 (projected). Number of new cases and age-standardised rates are presented as annual averages for each 3-year rolling period. ICD-10 codes C18-C20.

Projections are based on observed incidence rates and therefore implicitly include changes in cancer risk factors and diagnosis. Confidence intervals are not calculated for the projected figures. Projections are by their nature uncertain because unexpected events in future could change the trend. It is not sensible to calculate a boundary of uncertainty around these already uncertain point estimates. Changes are described as 'increase' or 'decrease' if there is any difference between the point estimates.

Small intestine cancer incidence rates (European age-standardised (AS) rates Open a glossary item) in England in females are similar in the most deprived quintile compared with the least, and in males are 22% higher in the most deprived quintile compared with the least (2013-2017).[1]

It is estimated that there are around 65 more cases of small intestine cancer each year in males in England than there would be if every deprivation quintile had the same age-specific crude incidence rates as the least deprived quintile.

No data are shown for females as the difference in age-standardised incidence rates between most and least deprived quintiles is not significant for females.
