Stomach cancer is the 17th most common cancer in the UK, accounting for 2% of all new cancer cases (2016-2018).[1-4]

In females in the UK, stomach cancer is the 19th most common cancer (1% of all new female cancer cases). In males in the UK, it is the 13th most common cancer (2% of all new male cancer cases).

35% of stomach cancer cases in the UK are in females, and 65% are in males.

Stomach cancer incidence rates (European age-standardised (AS) rate Open a glossary item) for persons are significantly higher than the UK average in Scotland, Wales and Northern Ireland and significantly lower than the UK average in England.

For stomach cancer, like most cancer types, differences between countries largely reflect risk factor prevalence in years past.

About this data

Data is for UK, 2016-2018, ICD-10 C16.

Last reviewed:

Stomach cancer incidence is strongly related to age, with the highest incidence rates being in older people. In the UK in 2016-2018, on average each year half of new cases (50%) were in people aged 75 and over.[1-4]

Age-specific incidence rates rise steadily from around age 45-49 and more steeply from around age 65-69. The highest rates are in in the 85 to 89 age group for females and males.

Incidence rates are significantly lower in females than males in a number of (mainly older) age groups. The gap is widest at age 70 to 74, when the age-specific incidence rate is 2.6 times lower in females than males.

Stomach cancer (C16), Average Number of New Cases per Year and Age-Specific Incidence Rates per 100,000 Population, UK, 2016-2018

For stomach 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.

Stomach cancer European age-standardised (AS) Open a glossary item incidence rates for females and males combined decreased by 55% in the UK between 1993-1995 and 2016-2018.[1-4] The decrease was of a similar size in females and males.

For females, stomach cancer AS incidence rates in the UK decreased by 54% between 1993-1995 and 2016-2018. For males, stomach cancer AS incidence rates in the UK decreased by 57% between 1993-1995 and 2016-2018.

Over the last decade in the UK (between 2006-2008 and 2016-2018), stomach cancer AS incidence rates for females and males combined decreased by 31%. In females AS incidence rates decreased by 29%, and in males rates decreased by 33%.

Stomach Cancer (C16), European Age-Standardised Incidence Rates, UK, 1993 to 2018

Stomach cancer incidence rates have decreased 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 remained stable, in 25-49s have decreased by 30%, in 50-59s have decreased by 49%, in 60-69s have decreased by 61%, in 70-79s have decreased by 57% and in 80+s have decreased by 53%.

Stomach Cancer (C16), European Age-Standardised Incidence Rates per 100,000 Persons Population, By Age, UK, 1993-2018

For stomach cancer, like most cancer types, incidence trends largely reflect changing prevalence of risk factors and improvements in diagnosis and data recording. Recent incidence trends are influenced by risk factor prevalence in years past, and trends by age group reflect risk factor exposure in birth cohorts.

The largest proportion of stomach cancer cases occur in the cardia, with much smaller proportions in the pyloric antrum and body of the stomach (2010-2012).[1-4]

The proportion of cases in the cardia is higher in males (34.0%) than females (19.7%) and there are no marked sex differences in other parts of the stomach.[1-4]

A large proportion of cases did not have the specific part of the stomach recorded in cancer registry data, or overlapped more than one part.[1-4]

Cases and percentages may not sum due to rounding

Stomach cancer incidence rates are projected to fall by 17% in the UK between 2014 and 2035, to 11 cases per 100,000 people by 2035.[1] This includes a larger decrease for males than for females.

About this data

Data is for: UK, 1979-2014 (observed), 2015-2035 (projected), ICD-10 C16

Projections are based on observed incidence and mortality rates and therefore implicitly include changes in cancer risk factors, diagnosis and treatment. It is not possible to assess the statistical significance of changes between 2014 (observed) and 2035 (projected) figures. 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.

Stomach cancer incidence rates (European age-standardised (AS) rates Open a glossary item) in England in females are 99% higher in the most deprived quintile compared with the least, and in males are 84% higher in the most deprived quintile compared with the least (2013-2017).[1]

It is estimated that there are around 1,300 more cases of stomach cancer each year in England than there would be if every deprivation quintile had the same age-specific crude incidence rates as the least deprived quintile. Around 490 of these cases are in females, and around 830 in males.

Age-standardised rates for White males with stomach cancer range from 14.1 to 14.7 per 100,000. Rates for Asian males are significantly lower, ranging from 5.2 to 8.5 per 100,000 whereas rates for Black males are significantly higher, ranging from 16.1 to 25.6 per 100,000. For females there is a similar pattern - the age-standardised rates for White females range from 5.5 to 5.8 per 100,000, while rates for Asian females are significantly lower, ranging from 2.7 to 5.0 per 100,000, and the rates for Black females are significantly higher ranging from 6.5 to 11.9 per 100,000.[1]

Ranges are given because of the analysis methodology used to account for missing and unknown data. For stomach cancer, 33,789 cases were identified; 18% had no known ethnicity.
