Breast screening (mammography)

This page has links to information in other languages.


A mammogram is a special X-ray of the breasts that looks for breast cancer. A mammogram can be done when you have no symptoms (this is called a screening mammogram), or to investigate lumps, or other concerning symptoms (this is called a diagnostic mammogram).

Women between the ages of 45 and 69 are entitled to a free screening mammogram every two years. If you're outside this age group you can still have screening but you'll have to pay for it yourself. In Canterbury, there's funding for extra screening for women at a higher risk of getting breast cancer.

In some circumstances, the radiologist (who interprets your X-ray) may recommend an ultrasound test to further assess the findings from your mammogram.

Health professionals don't recommend thermography for screening or assessing breast symptoms.
