Data Procession

Processing your data

Your doctor sends us some data about your person and disease. Here we tell you, what data are involved and how we process them.

On the one hand, we process information about your person (name, address, sex, date of birth, health insurance data). On the other hand, we collect important information about the cancer (time point, diagnosis, location, type and spread of the tumor) as well as about the course of the disease and therapy. These data are stored in a specially protected IT network.

The stored information on your cancer is statistically analyzed without reference to a name in the analysis center. Upon request, data can also be made available for specific purposes for scientific research. Your identity data (e.g. name, address) will only be released if you have given your prior consent. In this case, your physician or the cancer registry will contact you in advance. Furthermore, your attending physician can retrieve the medical data we have stored. This supports the exchange of information and contributes to the improvement of treatment quality.

If you do not want your data to be shared, you may raise an objection. Find out more about that here.

Usually, personal data are processed in the Bremen Cancer Registry only. However, in order to fulfill our tasks and obligations, it may be necessary for us to disclose the data stored about you to natural and legal persons, authorities, institutions or others. These data recipients are as follows:

  • Cancer registries of other federal states
  • Physicians obligated to report in Bremen
  • Your health insurance provider to perform the billing process for clinical cancer registries
  • Data recipients of scientific research projects (only if you have given your consent)


The recipient may only use the data for the requested project. Transfer to third parties is prohibited. Data must be deleted when they are no longer required for the project, at the latest when the project has been completed. The recipient must inform the trust center that the data have been deleted.

In the case of persons who have not yet reached the age of 18, the trust center of the Bremen Cancer Registry is authorized to transmit data to the German Childhood Cancer Registry, provided that consent has been given by the person concerned or his or her legal representative to this transmission.
