Summary
This study looks at 67 people in Denmark who had early-stage colorectal cancer removed during a colonoscopy or minor surgery. Doctors often recommend more surgery because of certain risk factors, but only about 15% actually have leftover cancer. The researchers are testing a blood test that looks for tumor DNA (ctDNA) a few days after the first removal. If the test works, it could help identify who truly needs more surgery and who can safely avoid it.
