CanRisk assessment tool

CanRisk is a new online assessment tool that can help decide which women have an increased risk of breast cancer. It takes about 10 to 30 minutes to complete the assessment with a doctor or nurse.

To use the tool, your doctor or nurse enters information about your whānau/family and your mother’s and father’s medical history. The tool then presents your risk prediction using a range of visual displays. This can help you understand how your risk compares to other women.

The tool uses New Zealand cancer incidence rates and is the best available way of calculating your risk.

When you make an appointment for a CanRisk assessment with your GP or practice nurse, they may ask you to prepare information for the appointment by completing this CanRisk questionnaire.
