​​Summary

The National Cancer Registration and Analysis Service (NCRAS), a part of NHS England, has assisted the cancer registration process for the Channel Islands since January 1996.

This is the 13th report from this service to incorporate data for Jersey and Guernsey and is an update using local 2016 to 2018 data for cancer incidence (new cases) and mortality. 

Information is provided on the age-standardised rates of incident (newly diagnosed) cancer and deaths from cancer for 20 cancer types / sites by three year rolling averages and for the latest available period. Data for Guernsey, the South West of England and, for the whole of England, is provided for comparison.

The report highlights those cancers which have a high or low rate compared to England or the South West based on aggregated data for 2016 to 2018.

The report also provides rates over time (since 2004) for each specific cancer type using counts and rates for three year periods.

Note on using Age Standardised Rates (ASR's)

Rates in the report have been produced using the 2013 European Standard Population (2013 ESP) which allows for rates between jurisdictions to be compared by removing any age structure differences in the population. This is the third report in the series to use this new standard, so it is important that rates are not compared to those in reports earlier than the Channel Islands Cancer Registration Report 2017. Previous reports used the 1976 standard population.

The age-standardised rates are also not comparable to rates calculated using other standard populations (such as the World Standard Population or the average England population).

 It is important that any rate comparisons are made on a like-for-like basis.​
