First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether naproxen or aspirin can increase immune cells in the colon to prevent cancer in people with Lynch syndrome, a genetic condition that raises cancer risk. About 40 participants will take one of these drugs or a placebo for a short time. Researchers will measure changes in colon tissue to see if these common painkillers can boost the body's natural defenses.
