Synthetic cancer patient data to help researchers gain insights
The Simulacrum is synthetic data that imitates cancer patient records held securely by the National Disease Registration Service (NDRS) at NHS England.
The data in the Simulacrum is made up entirely of artificial patient records. It does not contain any real patient information, so it cannot be used to identify a real person.
Simulacrum data is free to download and use, allowing anyone to analyse realistic record-level cancer data without risk of breaching patient confidentiality.
We have kept the data structure and statistical properties similar to the real data, so that it can be used to write and test queries that can run on the real data.
