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

In 2014, there were 7,900 new cases of in situ breast carcinoma in the UK: 7,868 (99.6%) in females and 32 (0.4%) in males, giving a female:male ratio of around 246:1.[1-4] The crude incidence rate shows that there are 24 new in situ breast carcinoma cancer cases for every 100,000 females in the UK, and 0.1 for every 100,000 males.

The European age-standardised incidence rate (AS rate) Open a glossary item of in situ breast carcinoma in females is significantly higher in England than in Wales, Scotland and Northern Ireland.[1-4] Rates for females in Scotland are lower compared with Wales. There are no other significant differences between the constituent countries of the UK.

About this data

Data is for: UK, 2014, ICD-10 D05

Female in situ breast carcinoma incidence is related to age, with the highest incidence rates being in females in their 50s and 60s. In the UK in 2012-2014, on average each year almost half (48%) of cases were diagnosed in females aged 60 and over.[1-4

Age-specific incidence rates rise steeply from around age 30-34, peak at age 50-54, drop slightly at age 55-59 before a second peak at 65-69, then decrease steeply until 75-79 and more steadily thereafter.[1-4]

There are too few male in situ breast carcinoma cases each year to examine incidence by age.

In Situ Breast Carcinoma (D05), Average Number of New Cases per Year and Age-Specific Incidence Rates, Females, UK, 2012-2014

For in situ breast carcinoma, most cases are identified through the breast cancer screening programme. Incidence increases rapidly at the age screening starts, as prevalent cases are identified, then falls rapidly at the age routine screening ends.

Most in situ breast carcinoma cases are intraductal, and there is a much smaller proportion of lobular in situ breast carcinomas (2010-2012).[1-4]

A small proportion of cases did not have the specific part of the breast recorded in cancer registry data.[1-4]

A quarter of women diagnosed with in situ breast carcinoma in England during 2006-2007 live in the least deprived areas of England, while only 13% live in the most deprived areas.[1] A similar distribution of cases by deprivation is also reported for invasive breast cancer.[1]

Last reviewed:

The proportion of incidence cases in White females with in situ breast carcinoma is significantly higher than for Asian or Black females.[1]

A similar ethnic profile is also reported for invasive breast cancer.[2]

Analysis included unknown data. For in situ breast carcinoma, 5,460 cases were identified; 28% had no known ethnicity.
