Registration details are not shared with any other parties. They may be used in the context of providing broad usage details, e.g. number of cancer risk calculations carried out by groups (e.g. Clinical Geneticists), to better inform us and funding bodies of the impact of the tool.

Please contact us if you would like your CanRisk account data to be deleted.

CanRisk Tool Data

Information entered into the CanRisk Tool (e.g. pedigree data, risk factors) only leaves the web browser when a risk calculation is run. To run the risk calculation the data is sent to our server machines. The individual's names in the pedigree are not sent, by the CanRisk tool, to the servers. On completion of the calculations the data transferred is removed from the server.

Secure Connection

This web site uses HTTPS which is a protocol for securing the communication between the web browser and the CanRisk web server. HTTPS connections are encrypted. The website automatically redirects you to HTTPS.

Contacting Us

Support requests are sent to the CanRisk service desk that is hosted on the Atlassian Cloud. When sending support requests please do not send sensitive or patient identifiable data. Data should always be sent in an anonymised format.
