About NCR data
The NCR data & figures application allows you to compile the incidence, prevalence, mortality and survival of any and (almost) every type of cancer in the Netherlands. The application will show a table with data and a graph. The option ‘all cancers’ includes all invasive types of cancer, excluding basal cell carcinoma of the skin.
The incidence, prevalence and survival data are derived from the Netherlands Cancer Registry. The mortality is derived from the data on causes of death of the Statistics Netherlands (CBS). These data are based on the cause of death as indicated by the physician.

Incidence is the number of new diagnoses per year. Incidence data currently shown in the app are based on data as available from the Netherlands Cancer Registry at the end of January 2021. Data from the two most recent years concern preliminary data, indicated by an asterix for the years 2019 and 2020. Data on incidence can be viewed for sex, age and region (province) of the Netherlands.
The total incidence concerns all invasive cancers, excluding basal cell carcinoma of the skin. Information on the incidence and prevalence of basal cell carcinoma is available up on request. Incidence data include the first invasive malignity per patient per cancer type only. This is in accordance with international agreements aimed at enabling comparison of data between countries. Data on all tumours per patient can be obtained through a data request.
Incidence data on breast cancer include all cases of invasive breast cancer and all cases of DCIS. While invasive breast cancer is deduplicated (i.e. only the first diagnosis per patient is counted), DCIS diagnoses have not been deduplicated. This means all DCIS diagnoses are counted, even if there are multiple diagnoses per patient.
Total incidence data of cancer on the urinary tract include Ta/Tis bladder cancer, as well as non-invasive renal pelvis and ureter cancer. Incidence data on bladder cancer also includes Ta/Tis-T4. While invasive bladder cancer is deduplicated (i.e. only the first diagnosis per patient is counted), non-invasive urinary tract cancer diagnoses have not been deduplicated. This means all cases of Ta/Tis and non-invasive diagnoses are counted, even if there are multiple diagnoses per patient.
Incidence data concerning thymomas seem unexpected; because this type of cancer was not properly signalled for several years, there is a decrease in incidence from 2012 throughout 2014.

When looking at incidence, you can select either the number, CR, ESR and/or WSR as a unit.
- Number: (an indication of) the absolute number of new diagnoses of a type of cancer in a certain period and/or region
- CR (Crude Rate): the number of new diagnoses per 100.000 persons per year. In our application, the CR describes the number of new diagnoses per 100.000 persons in the Dutch population. The CR gives a first indication of the occurrence of cancer in a certain population. It allows comparison through time or between regions. This enables us to see if there is a lower/higher cancer rate over time, or if a decrease/increase of absolute incidence is due to an increase or decrease in population.
- ESR (European Standardised Rate): the number of new diagnoses per 100.000 persons per year corrected for the age structure of the European population (ESP, 1976). The CR will likely be higher in a region with more elderly inhabitants, since cancer is more common among the elderly. Incidence data are therefore usually standardised for the age structure of the population. In European countries data are most commonly standardised using the European age structure, resulting in the European Standardised Rate.
- WSR (World Standardised Rate): similar to the ESR, but rather than the European age structure, the world age structure is used to standardise incidence data. This rate is very rarely used in Europe, since the world age structure is also largely determined by the age structure of Africa and Asia, which both largely differ from the age structure in Europe.
An update including an incidence prognosis for 2022 will follow on February 3d, 2023.
The application shows the prevalence of cancer. The prevalence of cancer describes all people alive on a certain date, who at some point have been diagnosed with a type of cancer. The application shows the 5-year prevalence by default. This is the number of people that are still alive 5 years after diagnosis. If you select ‘prevalence’ in the app, you can choose the 10-year prevalence and/or the 20-year prevalence as well.
The people included under prevalence are therefore a very diverse group, including both people who have been cured as well as people who have just been diagnosed with cancer. For example, the 5 year prevalence on January 1st 2020 concerns all living cancer patients who have been diagnosed in the previous 5 years. The 10 year prevalence and 20 year prevalence includes all living patients who have been diagnosed with cancer in the 10 or 20 years previous to January 1st 2020, respectively.
Prevalence data can be shown categorised by sex and/or by age category. The age category is based on the age of a patient on January 1st of the year from which is looked at the previous 5, 10 or 20 years.
Prevalence data currently shown in the NCR data app describe data as available from the Netherlands Cancer Registry at the end of January 2022. These data will be updated on February 3d, 2023.
The survival tab in the application shows the relative survival. It can be viewed for each year of diagnosis (1 year period or 10 year period), sex, age at diagnosis and the stage at diagnosis (TNM-classification). Survival data include data on all invasive cancers, except for data on children younger than 18 and data on persons who were discovered to have tumour only during obduction.
- The 5-year relative survival rate describes the percentage of patients alive 5 years after they have been diagnosed with a disease, divided by the percentage of people of the same sex and age expected to be alive in the general population at that time.
Survival data can be categorised by sex, age group at diagnosis and period of diagnosis for the 10 most recent years (i.e. from 2009 to 2018). The survival data can also be categorised by stage of disease at diagnosis (TNM classification), corresponding to the different editions of the TNM classification over the years. Periods of different TNM classifications are the 4th edition (1989-1992); 4th edition, 2nd revision (1993-1998); 5th edition (1999-2002); 6th edition (2003-2009); 7th edition (2010-2016) and 8th edition (2017-now).
Some types of cancer, like ALL, bone cancer and eye cancer are relatively common among children. However, the survival rate shown for these cancer types are only based upon data from adult patients. Survival amongst patients younger than 18 is generally better. Questions about incidence, prevalence and survival data on children with cancer can be sent to firstname.lastname@example.org
From 1989 nationwide coverage
Since 1989, our data covers the entirety of the Netherlands. This was the starting point of the Netherlands Cancer Registry. Survival data from 1961 until 1988 do not cover the whole Netherlands. Data from the 60’s and 70’s concern an increasing number of hospitals in the Eindhoven area. The data from the 80’s concern hospitals in the North-west and South-east of the Netherlands.
In light of the reliability of the data, we have not calculated survival rates for groups that include less than 50 patients. The calculations of survival per stage of disease are not standardised for age.
Survival data are based on the Netherlands Cancer Registry combined with vital status data from the municipal personal records database. Survival data are updated with vital status data until December 31th 2021 and will be updated again during the summer of 2023.
Cancer mortality describes the number of patients that die from cancer in a certain period of time (usually 1 year). Mortality data are derived from data on causes of death of the Statistics Netherlands (CBS). Data from the CBS are based on the cause of death as determined by the physician. The CBS categorises cancer types in their cause of death data according to the ICD10. Data on mortality can categorised by sex, age and region (province) of the Netherlands.
When looking at mortality data, you can select the number, CR, ESR and/or WSR as a unit.
- Number: (an indication of) the absolute number of deaths of (a type of) cancer in a certain period and/or region.
- CR (Crude Rate): the number of deaths per 100.000 persons per year. In our application, this describes the number of death per 100.000 persons in the Dutch population. The CR gives a first indication of cancer mortality in a certain population. It allows comparison through time or between regions.
- ESR (European Standardised Rate): the number of deaths per 100.000 persons per year corrected for the age structure of the European population (ESP, 1976). The CR will likely be higher in a region with more elderly (since cancer is more common among the elderly), therefore mortality is usually standardised for the age structure of the population.
- WSR (World Standardised Rate): similar to the ESR, but rather than the European age structure, the world age structure is used to standardise mortality. This rate is very rarely used in Europe, since the world age structure is also largely determined by the age structure of Africa and Asia, which both differ largely with the age structure in Europe.
Mortality data currently shown in the application concern data as available from the Statistics Netherlands (CBS) on December 2021. Mortality data from the year 2021 will be available on this website end of 2022.
Life time risk

Cancer in Europe
Have a look at the European cancer statistics, in which data of all European cancer registries is combined, at ECIS, het European Cancer Information System. Available are the cancer incidence and mortality for each European country.
Numbers of the cancer incidence, prevalence, mortality and survival of the Scandinavion countries are available in NordCan.
Check the Global Cancer Observatory of IARC for world wide statistics of trends and prognoses of cancer.
The IARC shows the numer of cancer cases caused by lifestyle factors. Amongst a wealth of figures are the numbers of cancer cases per continent:
- number of cancer cases caused by alcohol
- number of cancer cases caused by uv
- number of cancer cases caused by overweight
- number of cancer cases caused by infections, like HPV
