In situ breast carcinoma incidence statistics

Cases

New cases of in situ breast carcinoma each year, 2016-2018 average, UK.

 

Age

Peak rate of breast carcinoma in situ cases, 2016-2018, UK

 

Trend over time

Change in breast carcinoma in situ incidence rates since the early 1990s, UK

 

Breast carcinoma in situ incidence rates (European age-standardised (AS) rate Open a glossary item) for persons are significantly higher than the UK average in Wales and Northern Ireland, significantly lower than the UK average in Scotland and similar to the UK average in England. [1-4]

For breast cancinoma in situ, 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 D05.

Data was not available for Wales in 2018 for ICD-10 D05, therefore the 2018 data was extrapolated using the 2017 figures.

Breast carcinoma in situ incidence is related to age, with the highest incidence rates being in the 65 to 69 age group. In the UK in 2016-2018, on average each year around a tenth of new cases (9%) were in people aged 75 and over.[1-4] This is a lower proportion of cases in older age groups compared with most cancers.

Age-specific incidence rates in females, rise steeply from around age 35-39, then decrease steeply from age 65-69 and decrease steadily from age 75-79. In males rates increase from age 35-39. The highest rates are in in the 65 to 69 age group for females and the 80 to 84 age group for males.

Incidence rates are significantly higher in females than males in a number of (mainly older) age groups. The gap is widest at age 45 to 49, when the age-specific incidence rate is 888 times higher in females than males.

Breast carcinoma in situ (D05), Average Number of New Cases per Year and Age-Specific Incidence Rates per 100,000 Population, UK, 2016-2018

For breast carcinoma in situ, most cases are identified through the breast screening programme. Incidence peaks first when routine screening starts at age 50, with a brief drop shortly after which reflects the diagnosis of prevalent cases at first-time screening. Incidence then falls rapidly when routine screening ends at age 70.

Breast carcinoma in situ European age-standardised (AS) Open a glossary item incidence rates for females and males combined increased by 200% in the UK between 1993-1995 and 2016-2018.[1-4] The increase was larger in females than in males.

For females, breast carcinoma in situ AS incidence rates in the UK increased by 201% between 1993-1995 and 2016-2018. For males, breast carcinoma in situ AS incidence rates in the UK increased by 101% between 1993-1995 and 2016-2018.

Over the last decade in the UK (between 2006-2008 and 2016-2018), breast carcinoma in situ AS incidence rates for females and males combined increased by 31%. In females AS incidence rates increased by 32%, and in males rates remained stable.

Breast Carcinoma In Situ (D05), European Age-Standardised Incidence Rates, UK, 1993 to 2018

Breast carcinoma in situ incidence rates have increased overall in all broad adult age groups in females in the UK since the early 1990s.[1-4] Rates in 25-49s have increased by 187%, in 50-64s have increased by 120%, in 65-69s have increased by 617%, in 70-79s have increased by 508% and in 80+s have increased by 480%.

Breast Carcinoma In Situ (D05), European Age-Standardised Incidence Rates per 100,000 Female Population, By Age, UK, 1993-2018

Breast carcinoma in situ incidence trends probably reflect the effective implementation of the UK breast screening programmes in the late 1980s, and subsequent extensions to the screening-eligible age group and improvements in screening methods – most cases are identified through the screening programme.[5] Changing prevalence of risk factors probably also plays a part.[5]

The most common specific location for in situ breast carcinomas in the UK is in the cells lining the milk ducts (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.

Breast carcinoma in situ incidence rates (European age-standardised (AS) rates Open a glossary item) in England in females are 28% lower in the most deprived quintile compared with the least, and in males are similar in the most deprived quintile compared with the least (2013-2017).[1]

It is estimated that there are around 900 fewer cases of breast carcinoma in situ each year in England in females 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 males as the difference in age-standardised incidence rates between most and least deprived quintiles is not significant for males.
