Frequently asked questions

  1. Do I need permission to use and publish from NORDCAN?

    No, Cancer statistics in tables and figures are freely available, and you are allowed to use it with the recommended references to NORDCAN. Tables can be copied using the text file option and for figures/graphs right-click to see the options. See the front page for specific information about references.

  2. Can I get more detailed data if I ask for a password?

    No, All the data you can access with a password can also be found in NORDCAN’s publicly available facilities, and we prefer that you use these. However, if you want to export data to another program for modeling or special graphics, the download option of the tabulated raw data to a text file can be used. To download, you need to ask for a password from the Secretariat. We ask you to provide contact information, title of project, data you wish to download, planned use or publication and a time plan. The information can help us improve NORDCAN to support your purposes in the future. We also ask you to supply us with copies or references to your publications using NORDCAN-data. To get continued financial support for NORDCAN, we need to document the use.

  3. Can I get data on individual cancer patients from NORDCAN?

    No, NORDCAN only provides tabulated data. If you want to retrieve individual data, you need to make a request at each national cancer registry. Contact information can be found under “Contacts” in the menu.

  4. Can I acquire tabulated data for other combinations of ICD-10 and morphology than the diagnosis groups shown in NORDCAN?

    You can see the available diagnosis groups, called entities, as defined by ICD-10 codes in ”The Cancer Dictionary” in the menu. If you need other combinations, you have to acquire data from each national cancer registry. Contact information can be found under “Contacts” in the menu.

  5. Why do some of the numbers differ from the numbers reported in national annual reports?

    We make versions according to international rules of the national data sets (using IARCcrgTools and rules for counting multiple cancers) to make as valid comparisons as possible between countries and over time. The national cancer registries use new information about earlier reported patients. This can have an influence on incident numbers back in time.

  6. Are comparisons between countries and over time always valid?

    We make international versions of the national datasets (using IARCcrgTools and rules for counting multiple cancers) to make as valid comparisons as possible between countries over time. However, change in classifications over time and differing national coding rules do not always make this possible. Description of problems with comparability can be found under the heading ”Notes” below the map with regions in ”The NORDCAN database”.

    Age-standardisation. Population numbers and age distribution differ over time and between countries, so to make valid comparisons of incidence, mortality, prevalence and survival, we offer different age-standardisations. See more description in “Glossary of terms” in the menu.

  7. Are regional data available?

    Data for up to 6 regions are available for each country. A map showing the available regions can be seen at the menu point “The NORDCAN database”. Animated cancer maps based on municipality data can be found under ONLINE ANALYSIS, Incidence/Mortality as the point Cancer maps.

  8. How often are animated maps and survival updated?

    We have funding from NCU to update the animated maps and the survival data every fifth year, but a special grant from Danish Cancer Society makes it possible to update survival data with each update in 5-year periods of diagnosis. Periods move 1 year with each update so we always can supply survival for the latest available 5-year period of year of diagnosis.
