Machine reading boost set to cut thousands of unnecessary breast cancer call-backs

Since its rollout, the technology has analysed more than 19,000 images and helped detect over 130 cancers.

BreastScreen NSW will expand the use of its machine reading technology to all first-time participants after a successful 12-month trial showed it reduced unnecessary call-backs without compromising cancer detection.

The system, first introduced to assess selected mammography images from women aged 50–59, has “delivered excellent results”, Health Minister Ryan Park said.

Officials say the increased accuracy is easing stress for women who would otherwise be asked to return for additional tests such as ultrasounds or needle biopsies. By the end of 2025, around 500 women — or about 20 per cent fewer first-time screeners — are expected to avoid call-backs thanks to the expanded program.

Park said the expansion would ensure “more women have access to this life-saving technology”, adding that reducing the impact of breast cancer in NSW remains a priority. “I’d like to thank the BreastScreen NSW team for their world-leading work,” he said.

BreastScreen NSW was the first population-based screening program in Australia to deploy the technology, which supports radiologists by providing an additional layer of analysis. Every image continues to be reviewed by at least one radiologist.

NSW Chief Cancer Officer Professor Tracey O’Brien AM said the agency undertook extensive evaluation before introducing the system, describing the outcome as better than anticipated.

“We did the groundwork to ensure this innovative technology would benefit women and radiologists. The results so far have exceeded our expectations,” she said.

“Fewer women are now experiencing stress and anxiety as they aren’t being called back for testing. At the same time we are ensuring care and support is being given to the women who need it most.”

She urged women to take breast cancer seriously and book their screening appointment, saying the technology is helping ensure detection “in its earliest stages”.

The benefits of early detection are well known to Donna, who was diagnosed with breast cancer at 60 after a routine screen. With a strong family history — both her sisters were diagnosed before her — she said she made screening a priority.

“Fortunately my cancer was caught through a breast screen early and now I tell everyone if the BreastScreen NSW bus comes to your area go get checked,” she said.

“The first time can be a bit of a shock but after that it just becomes routine, something you do for your health and your life.” She encourages women who may hesitate:

“The earlier cancer is found the better… If you’re hesitating I’ll say what I tell my friends, ‘Come on I’ll go with you.’”

Women aged 50–74 are encouraged to have a breast screen every two years, while Aboriginal and Torres Strait Islander women are advised to begin at 40. Those who notice changes in their breasts, such as a lump, should see a doctor promptly.

Appointments can be made by calling 13 20 50 or via the BreastScreen NSW website.
