The purpose of the National Cancer Data Set is to advise ORGANISATIONS within the National Health Service on a transferable set of data. These data will meet the needs of clinical audit, assist in the generation of National Performance Indicators and will allow outcome assessment.

By clicking on the data element text within the data set opposite, the selected data element definition will be displayed.

Any text within the displayed definition which is in blue and uppercase is the name of a class, attribute or data element; business definitions appear in Title Case and all if clicked on will display the definition for that class, attribute, data element or business definition.
