Mayo Study Finds 1,825 Pancreatic Cancer Patients Lost Fat Faster Before Diagnosis

Summary
Three years before diagnosis, pancreatic cancer patients showed steeper declines in visceral and subcutaneous fat on routine abdominal CT scans than 3,650 matched controls, according to a Mayo Clinic study in Pancreatology.
AI measured body composition across scans from Mayo sites in Arizona, Florida and Minnesota; muscle-loss differences appeared mainly in the final 12 months, suggesting fat changes may emerge earlier.
The researchers said the method is not a clinical test: it was retrospective, showed only moderate ability to distinguish future cancer patients, and has not been validated in other health systems or prospective follow-up.
Current guidance remains unchanged—adults without symptoms should not seek CT screening for pancreatic cancer, while people with strong family history or inherited risk may still qualify for high-risk surveillance.
The findings add to a broader push for earlier detection, including Mayo work on rising blood sugar before diagnosis and trials combining imaging, records and algorithm-based screening.
