You can find more information about the breast screening program in NSW.

Data coverage

BreastScreen NSW collects information on breast screening services within the program for women aged 40 years and over in NSW. Women aged 50  74 years are actively recruited to attend the service via an invitation when they turn 50, and a reminder letter every two years.

Data sources

The BreastScreen NSW Information System stores women’s breast screening history, which is used to deliver more accurate mammography reading results, and acts as a safety net to remind women when their next breast screen is due.

It also provides greater efficiency with the analysis of results, and assists us to further understand breast cancer and the best possible treatment methods.

Electoral Roll data and Medicare data are provided to the Cancer Institute NSW by the NSW Electoral Commission and the Australian Government Department of Human Services respectively, for the purposes of ensuring the accuracy of records on people who participate in (or who are eligible to participate in) cancer screening programs.

Data are provided to the Cancer Institute NSW by the Registry of Births, Deaths and Marriages for the purpose of ensuring that deceased people are not contacted regarding cancer screening programs.
