AI finds signs of pancreatic cancer before tumors develop: An artificial intelligence model from the Mayo Clinic detected abnormalities on scans up to three years before patients were diagnosed. It's being evaluated in a clinical trial.

By the time doctors detect pancreatic cancer, it’s often too late to treat effectively. But a new study suggests that artificial intelligence might be able to find signs of the disease before tumors are visible on a scan. An AI model developed at the Mayo Clinic in Rochester, Minnesota, detected abnormalities on patients’ CT scans up to three years before they were diagnosed with pancreatic cancer, according to research published this week in the journal Gut. The scientists behind the model, which is now being evaluated in a clinical trial, trained it by feeding it CT scans from patients who...
