Cancer Prevalence

The following dashboard provides figures for observed (or limited duration) cancer prevalence in England. This observed prevalence counts the number of people that were diagnosed with a cancer between 1995 and 2017 and were still alive on the 31st December 2017.

Cancer prevalence is useful to understand how many people in the population are living with a cancer diagnosis. There are different ways to measure different types of cancer prevalence - a summary of the different methods is available here .

Cancer prevalence is a product of both cancer incidence and survival and should be interpreted with these factors in mind, especially if making comparisons across tumour groups or populations. For example, a cancer with high incidence but poor survival outcomes could have similar prevalence to a tumour type with lower incidence but high survival rates.

The dashboard presents prevalence counts and rates for Clinical Commissioning Groups, Sustainability and Transformation Partnerships and Cancer Alliances across England, broken down by population demographics and for different tumour types.

Observed vs. Complete Prevalence

This measure of cancer prevalence is referred to as ‘observed’ or ‘limited duration’ because it only considers cancers that were diagnosed after 1995, when detailed cancer registrations became available. Estimates of complete prevalence have previously been generated by the National Cancer Registration and Analysis Service (NCRAS) partnership with Macmillan Cancer Support, and more information can be found here.

The Cancer Prevalence Dashboard was generated by the NCRAS partnership with the Transforming Cancer Services Team for London (TCST), and is based on the recently published 2017 London Prevalence Dashboard.
