Abstract

Ongoing linkage of cancer data to screening data can be used to monitor the performance of the NCSP. Our finding that 80% of potentially preventable cervical cancers involve women who are not enrolled in the Programme or who have been only infrequently and irregularly screened, confirms that improving Programme coverage (currently around 72%) remains a priority. Further investigation (phase 2) is required for the small number of women who develop cervical cancer despite regular screening (average of 21 per year, or approximately 20% of eligible cases), to distinguish interval cancers from possible Programme quality issues.
