Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what data has been published from version 8 of the Cancer Outcomes and Services Dataset (COSD); and whether that includes data on the number of people diagnosed with secondary breast cancer.

Version 8 of the Cancer Outcomes and Services Dataset (COSD) applies to cancer data submitted to Public Health England (PHE) from April 2018.

Data from this period is included in National and Official Statistics, such as the case-mix adjusted percentage cancers diagnosed at stages 1 and 2 by the Clinical Commissioning Group in England (https://www.gov.uk/government/statistics/case-mix-adjusted-percentage-cancers-diagnosed-at-stages-1-and-2-by-ccg-in-england). In addition, monthly COSD data reports are available to the NHS via a secure reporting website.

PHE published data on secondary breast cancer from v8 of the COSD in November 2020. This information is available here:
