Researchers Identify Link Between Rectal Bleeding, Colon Cancer
Rectal bleeding raises colon cancer odds by more than eight times in adults under 50, with 44% diagnosed at early stages, researchers said.
- On Tuesday, researchers at the American College of Surgeons annual meeting in Chicago reported that rectal bleeding increased colon cancer odds more than eightfold in people younger than 50, analyzing 443 colonoscopies at the University of Louisville Health System from 2021 to 2023.
- Amid rising early-onset rates, researchers note that the U.S. Preventive Services Task Force recommends screening starting at age 45, yet 70% of patients diagnosed had no family history, indicating a screening gap for younger adults.
- Age-Specific data show patients aged 35 with rectal bleeding are 8.5 times likelier to have colorectal cancer, and nearly 9 out of 10 diagnosed patients underwent colonoscopy due to symptoms.
- Researchers hope doctors will use these results to steer younger adults at risk toward a colonoscopy, and adults with rectal bleeding are advised to ask their doctor for one, though findings are preliminary until peer-reviewed.
- Nonhereditary risks appear important as only 13% of cases had genetic markers for colon cancer and former smokers were nearly twice as common among early-diagnosis patients.
