Calculate your risk
About this calculator
This user-friendly, interactive calculator is intended for use by women who have not had breast or ovarian cancer. It will help you to gain a good understanding of your level of risk for breast cancer compared to another woman of your age group. National Breast Cancer Centre* has based the questions in this calculator on the most important risk factors for breast cancer based on an up-to-date review of international evidence.
The calculator only takes a few minutes to complete, and the relevant risk factor is explained at each stage.
It is important to remember that the results of this calculator are not a guarantee of your risk levels, and that all women are at risk for breast cancer, no matter what their risk category. Some women at increased risk never develop breast cancer, and some women at low risk may develop the disease.
* In February 2008, National Breast Cancer Centre (NBCC), incorporating the Ovarian Cancer Program, changed its name to National Breast and Ovarian Cancer Centre (NBOCC). In July 2011, NBOCC amalgamated with Cancer Australia to form a single national agency, Cancer Australia, to provide leadership in cancer control and improve outcomes for Australians affected by cancer.
