Question to the Department of Health and Social Care:
To ask the Secretary of State for Health and Social Care, what proportion of bowel cancer patients were diagnosed at stage I or II in each year since 2010.
The following table shows the proportions of staged diagnoses of bowel cancer by diagnosis year from 2013 to 2020 the most recent fully registered diagnosis year.
Year Stage I Stage II Stage III Stage IV
2013 18% 27% 29% 27%
2014 18% 27% 30% 26%
2015 18% 26% 30% 26%
2016 19% 26% 30% 26%
2017 18% 26% 30% 26%
2018 19% 25% 30% 25%
2019 20% 25% 31% 24%
2020 18% 25% 31% 26%
For diagnosis years before 2013, the completeness of staging data of stageable cancers, including bowel cancer, was below 70%. Because of the high level of missing stage data, it is not possible to produce reliable estimates of the stage distribution for the diagnosis years 2010 to 2012.
