Summary

This study looks at whether a simple blood test can find tiny bits of cancer DNA left in the body after colorectal cancer surgery. The goal is to identify patients at high risk of the cancer coming back, so doctors can adjust treatment early. Over 3,000 participants are being followed for three years to see if the test helps improve survival without cancer returning.
