Summary

This study looks at whether a simple blood test that checks for tumor DNA can help decide which patients with diverticulitis (a colon inflammation) actually need a colonoscopy to rule out colorectal cancer. Researchers will collect blood from 220 patients and compare the test results with colonoscopy findings. If the blood test works well, it could reduce the number of unnecessary colonoscopies and save healthcare costs.
