Incidence > An incident case of cancer is a new case of cancer, counted once when the cancer is diagnosed. Base numbers of cases, crude and age standardised rates can be found by following the links below.
Click here for numbers of new cases of cancer. Numbers can be presented for different cancer sites, different time periods, and different geographies. Numbers are useful when trying to estimate the burden of cancer - how many tumours have been diagnosed?
Click here for crude cancer incidence rates. Rates can be presented for different cancer sites, different time periods, and different geographies. Crude rates are useful when trying to compare the incidence of cancer in two populations. Because of the strong link between age and risk of cancer, crude rates are often highest in populations with a high proportion of elderly people.
Click here for age-and-sex standardised cancer incidence rates. Rates can be presented for different cancer sites, different time periods, and different geographies. Standardised rates correct for the difference in incidence in cancer because of age and sex. They are useful for comparing underlying cancer risk in populations with different age/sex profiles.
Incident cases of cancer are counted for each separate primary tumour. One person may be diagnosed with more than one tumour, and would then appear twice in the incidence statistics. Recurrences of a previous cancer are not counted as new incident cases.
Standardised rates are standardised according to an approximate 2013 European Standard Population. The five year age bands in the ESP are grouped into the age bands published on this tool to make a standard population for these age bands.
Data presented are taken from the National Cancer Registration Service Cancer Analysis System, snapshot CAS2004.
Populations data has been sourced from ONS Mid 2018 Lower Super Output Area Population Estimates, released 26/06/2019.
Postcode lookups are as defined in the ONS National Statistics Postcode Lookup (NSPL) as of May 2019.
