AI-assisted breast screening helps radiologists detect cancer earlier

When Linda went for her routine mammogram at North York General (NYG), she expected it to be just another screening appointment to check off her list. Her images were reviewed by a radiologist, and at first glance, nothing seemed out of the ordinary.

But behind the scenes, NYG was piloting a new artificial intelligence (AI) tool called Genius AI Detection. The technology, developed to act as a second set of eyes for radiologists, flagged a 3mm lesion that had previously gone undetected.

Because of that second look, Linda’s care team was able to act quickly, arranging further imaging, a biopsy, and treatment. She underwent cryoablation, a minimally invasive procedure that freezes and destroys cancer cells, which successfully treated the cancer.

Linda’s story is anonymized to protect her privacy, but the lesson it illustrates is powerful. Thanks to the generosity of our donors and support from the North York General Foundation, artificial intelligence is already changing lives at NYG, and Linda’s story demonstrates the real-world potential of AI to improve patient outcomes.

“By giving radiologists another set of highly advanced eyes, Genius AI Detection solution is helping us detect potential cancers earlier,” said Dr. Ryan Margau, NYG chief radiologist and medical director of the Department of Medical Imaging. “That has a direct impact on survivorship because the earlier we find it, the better the chances for our patients.”

North York General is setting a new standard in breast cancer care. NYG is the first and one of the very few sites in Ontario to offer tomosynthesis (3D mammography) as the standard screening method for every patient and the first site in Canada to integrate Genius AI Detection technology into its breast screening program. In addition, it is the only hospital in Ontario providing cryoablation as a treatment option for breast cancer.

NYG is proud to be the only breast cancer centre in Canada to be internationally accredited by the National Accreditation Program for Breast Centers (NAPBC), which recognizes our commitment to the highest standards of quality and patient care. Together, these innovations are redefining what early detection and breast cancer treatment can look like, improving outcomes and recovery experiences.

Genius AI Detection solution is powered by deep learning and integrated into Hologic Dimensions Mammography Systems. Its algorithm combs through every slice of breast tomosynthesis or 3D image sets, looking for subtle patterns that could suggest abnormalities like cancer. It is trained to identify three main categories of concern: calcifications, masses, and tissue distortions, or any combination of these.

When something suspicious is detected, the system highlights the area for the radiologist to evaluate. It also generates case-level metrics, flagging higher-risk cases for immediate review. In doing so, Genius AI Detection technology enhances the expertise of radiologists, providing an added layer of safety so that no detail is missed.

With the Genius AI Detection solution, radiologists can prioritize their workloads more effectively and focus their expertise where it is needed most. For patients, this translates into early detection and potentially faster access to treatment, which can make all the difference.

“Genius AI Detection technology was created to give radiologists greater confidence in their interpretations while helping patients get answers sooner,” said Jay Malayny, Hologic vice president & general manager, Canada & LATAM. “Seeing North York General lead the way by integrating our technology into routine screening is inspiring. They are setting a new standard for how AI can elevate breast cancer care from the outset.”

At North York General, adopting AI tools is not about chasing the newest technology, but about enhancing the delivery of care. The hospital’s approach to AI adoption has always been thoughtful and deliberate with a clear focus on solving practical challenges for both clinicians and patients while safeguarding privacy and security. Whether supporting clinicians or improving patient experiences, NYG remains committed to a transparent and ethical approach to AI that is firmly aligned with our values.

“By integrating AI into our clinical workflows, we’re able to reduce the administrative burden on providers, support better clinical decision-making, and ultimately enhance the quality of care for our patients,” said Dr. Phil Shin, NYG chief medical information officer.

As one of the first hospitals in Canada to bring AI into everyday clinical practice, NYG is shaping what the future of digital health looks like. From pioneering Canada’s first cloud-based electronic health record to leading the way in AI adoption, North York General has built a reputation for turning innovation into impact. Genius AI Detection solution is the latest example of how NYG is translating digital transformation into meaningful outcomes at the bedside.

“Digital initiatives like AI are key enablers to our new 10-year Strategic Plan,” said Duska Kennedy, NYG vice president strategy, digital health and chief digital officer. “They allow us to deliver the best possible care by excelling in specialized areas, responding to the diverse needs of our community, and equipping our teams with the very best technology available. That combination is what will truly set us apart for our patients and families.”
