Not all cancer types are represented within the tool, as we have focused on a selection of common and rarer cancers. In some instances, where the data is cut by age groups or for certain cancer types, we have excluded small numbers in order to maintain the privacy of the cancer patients behind the figures.
The Welsh Cancer Intelligence and Surveillance Unit (WCISU) is the National Cancer Registry for Wales and its primary role is to record, store and report on all incidence of cancer for the resident population of Wales wherever they are treated.
On 12 July 2018, we published our latest available cancer incidence and prevalence statistics for the GP (primary care) Cluster Networks in Wales for diagnoses up to 2015.
Throughout this website tool, we refer to 'WCISU' in short rather than by the full name. Macmillan works in partnership with WCISU.
- Health Board
There are 7 Health Boards in Wales. A Health Board (HB) is an administrative unit within the National Health Service in Wales. Health Boards were first established in Wales in 2003.
- Local authorities (councils)
Local authorities play a central role in governing Wales, providing the local leadership and services necessary for their communities, including healthcare provision. There are 22 Local Authorities in Wales, established since 1996.

The majority of the indicators presented in the tool by Local Health Board (prevalence, incidence and mortality) or by Local Authority (prevalence, incidence and mortality) are reported based on patients' postcode of residence at the time of their cancer diagnosis.
