Risk Factors

There are a number of factors that can increase your individual risk of developing breast cancer.

These include personal factors such as:

  • being female
  • ageing
  • if you’ve had a previous diagnosis of breast cancer
  • your family history
  • your individual breast density.

There are also lifestyle factors that contribute towards your risk that you can actively manage and lessen. These risks include:

  • your diet
  • how often you exercise
  • if you smoke regularly
  • if you drink alcohol.

If you want to assess your individual risk, you can speak with your doctor or use the risk assessment tool available from  Cancer Australia.

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.
