The Cancer Registry


Primary variables


Anatomical localisation

Cancer diagnosis

Cancer type


Date of birth



Municipality of residence

Spread of the disease within the first four months of diagnosis date


The Cancer Registry (CAR) is an incidence register containing details of new cases of cancer in Denmark since and including 1943. The registry also has details about the date of diagnosis, anatomical issues, type of cancer and how the diagnosis was made. Until 2003, reports were in paper form but from 2004, the Cancer Registry switched to electronic reporting and also switched to the 'automatic cancer logic' coding system.

It should be noted that reporting to the Cancer Registry was on a voluntary basis until 1987 after which it became obligatory. The registry is updated once a year and updated data for the previous year is available in December.
