AI in cancer screening is transforming the way doctors detect cancer, offering new hope for earlier and more accurate diagnoses. At Allina Health, physicians have started using artificial intelligence tools as a second set of eyes to double-check results, improve efficiency, and ultimately help save lives. These AI tools don’t replace human expertise, but they enhance it — making screenings more reliable and reducing the chances of missed cancers.
In a world where technology continues to evolve rapidly, AI is making an especially significant impact in healthcare. By supporting doctors during screenings and tests, AI can spot warning signs that might otherwise go unnoticed. This is especially important for conditions like cancer, where early detection is key.
One of the most promising uses of AI in cancer screening at Allina Health is in the detection of colon cancer. At the Cambridge Medical Center, doctors are using a tool called GI Genius during colonoscopy procedures. This AI-powered system analyzes video footage in real time and compares it to a massive library of over 13 million images of polyps — the small growths that can sometimes develop into cancer.
When GI Genius detects a possible polyp or anything unusual, it highlights the area on the screen, prompting the doctor to examine it more closely. It’s like having a digital assistant that never blinks or gets tired, working alongside the physician to make sure nothing is missed.
Dr. Stanley Dick, a gastroenterologist at the center, performs more than 1,100 colonoscopies every year. He says GI Genius has helped him identify small and subtle polyps that might not be visible to the human eye. According to him, AI doesn’t replace the doctor’s decision-making — instead, it adds an extra layer of confidence to the screening process.
Colorectal cancer is the third most commonly diagnosed cancer worldwide and is among the leading causes of cancer-related deaths. However, it’s also one of the most preventable and treatable forms of cancer — especially when detected early. That’s why accurate and early detection tools like GI Genius are so important. As cases of colorectal cancer in people under age 55 continue to rise, health authorities have lowered the recommended screening age from 50 to 45, making effective tools like AI even more crucial.
Allina Health is also using AI in groundbreaking ways to fight breast cancer. Through a clinical partnership with a tech company, the Allina Health Cancer Institute is participating in a trial that uses AI to analyze blood samples and detect cancer.
This method involves creating a 3D holographic image of cells taken from a simple blood draw. The AI system then scans the image and distinguishes healthy cells from those that show signs of cancer. This process makes it possible to detect cancer much earlier than traditional imaging methods like mammograms or biopsies.
Dr. Badrinath Konety, president of the Allina Health Cancer Institute, sees this as the future of cancer diagnostics. By studying the behavior and traits of cancer cells without needing invasive procedures, doctors can potentially catch the disease sooner and create personalized treatment plans that are more effective.
This trial also opens the door for better monitoring of how cancer responds to treatment and whether it might return. With AI, doctors can keep a close eye on the disease without needing frequent scans or biopsies.
Radiologists at Allina Health are also benefiting from the growing role of AI in medical imaging. Today, AI systems are able to scan X-rays, MRIs, and CT scans and identify small abnormalities that human eyes might overlook — especially in busy hospitals where hundreds of images need to be reviewed every day.
Dr. Konety explains that in most cases, AI agrees with the radiologist’s findings, but in some situations, it highlights areas that deserve a second look. That small margin can make a big difference. AI doesn’t make the final call, but it ensures that radiologists don’t miss anything critical.
For example, if a small shadow appears on a lung scan that could be an early sign of cancer, AI can mark it for review. That kind of vigilance gives patients a better chance at early diagnosis and effective treatment.
This AI-powered “double-check” is also helpful when it comes to training younger radiologists and standardizing results across different hospitals. It brings consistency to the diagnostic process and offers support when decisions are especially complex.
Lung cancer, like many other forms of cancer, benefits greatly from early detection. When caught early, the survival rate for lung cancer increases dramatically — but symptoms often don’t show up until the disease has already progressed.
That’s where AI comes in. At Allina Health, lung cancer screenings are being improved through AI systems that analyze CT scans and look for tiny nodules in the lungs. These nodules can be harmless, but in some cases, they may be an early sign of cancer.
The AI tool acts like a second reader, reviewing the scans and highlighting areas of concern. If the AI finds something questionable, the radiologist can investigate further. This partnership between human and machine improves the chances of spotting cancer before it spreads.
Additionally, the data collected by AI tools can help create better screening guidelines in the future. As the technology learns from each scan, it becomes more accurate and more useful for diagnosing all kinds of cancer, not just lung-related cases.
While AI is powerful, doctors at Allina Health emphasize that it will never replace human judgment. Instead, it supports and strengthens it. Doctors make the final decisions, but AI gives them better information and helps them work more efficiently.
This collaboration between humans and machines is helping doctors feel more confident in their diagnoses and ensuring that patients receive the best possible care. AI reduces uncertainty, speeds up the review process, and helps prevent missed diagnoses — all while keeping the patient at the center of care.
It’s not just about using flashy new technology. It’s about using smart tools that truly make a difference in people’s lives.
The use of AI in cancer screening is still evolving, but its impact is already clear. At Allina Health, the success of AI-assisted screenings shows how technology can improve both accuracy and peace of mind for patients.
As AI tools continue to develop and learn, they will become even more powerful partners for doctors. Future versions may be able to predict which patients are at higher risk for cancer, suggest treatment options, and track progress in real time — all based on massive datasets and machine learning.
What’s exciting is that these advances don’t just stay in research labs. They’re already being used in real hospitals, helping real people. And for those facing a cancer diagnosis or a routine screening, that extra layer of support can make all the difference.
Conclusion
The integration of AI in cancer screening at Allina Health is a perfect example of how technology and healthcare can work hand-in-hand. By adding an intelligent layer of support to existing medical procedures, AI helps doctors do their jobs better, faster, and more accurately.
From colonoscopies to blood tests, and from X-rays to CT scans, AI is becoming a trusted companion in the fight against cancer. And while it won’t replace doctors anytime soon, it’s proving to be an invaluable ally in the mission to catch cancer early and save lives.
As more hospitals adopt these technologies, we can expect cancer detection to become faster, more accurate, and more personalized — marking a hopeful step forward in global health.
