Cities in the north of England have some of the lowest survival rates.
Cancer Research UK has launched a new tool that allows people to compare cancer statistics in their area with those in the rest of the country.
It hopes the local data will help doctors and politicians tackle the specific problems in their patch.
There is separate data for England, Scotland, Wales and Northern Ireland.
In Scotland, the greater Glasgow area had the highest cancer mortality while Shetland had the lowest.
Mortality was much higher in Belfast than the rest of Northern Ireland.
