Definitions
The number of new cancers reflects the number of primary tumours rather than the number of individuals with cancer.
Data calculation/treatment
Rates are expressed per 100,000 population and age-standardised to the WHO World Standard Population. The population is based on official estimates as at 31 December.
Limitations of the data
Caution is advised when interpreting rates derived from small numbers as they may fluctuate markedly from year to year.
Exclusions
Multiple cancers with the same site and same morphological group are excluded.
