From the BreastScreen website:

BreastScreen Victoria is a population screening program, which means we offer our service to the eligible group in the community proven to benefit most from screening. Breast screening is known to be most effective in reducing breast cancer deaths and the impact of treatment among women in the 50-74 age group.

BreastScreen Victoria (BSV) is a free service for women with no breast symptoms. We invite women* aged 50 to 74 years old to have a breast screen regularly, usually every two years.

If you have a breast symptom or changes in the look and feel of your breast, you should see your doctor as soon as possible. Your doctor may then request a diagnostic mammogram for you, which looks at your specific problem.

A breast screening mammogram (or breast screen) checks for breast cancer. At your screening appointment, the radiographer will take two images of each breast, which are later examined by two or more radiologists.

In a small number of women, the screening mammogram will show possible signs of breast cancer. If this happens after your breast screen, you will be contacted to attend a second appointment which is called an assessment. An assessment appointment involves further testing such as x-rays, ultrasound, biopsies and clinical examination, so that we can reach a diagnosis. These tests are all performed at our assessment clinics. Our team will decide which tests you require on the day. *including trans women, and trans men and non-binary people who fit the eligibility criteria.
