Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what recent estimate he has made of the proportion of new diagnoses of recurrent and metastatic breast cancer which hospital trusts are submitting to the Cancer Outcomes and Services Dataset (COSD).

No recent estimate has been made.

It is a requirement for hospital trusts to report on new diagnoses of recurrent and metastatic breast cancer. Public Health England reports data on recurrent and metastatic breast cancer to National Health Service trusts to support improved data quality and ascertainment. Non-compliance with data standards is monitored through the local clinical commissioning groups.
