Testing stool samples to detect colorectal cancer early

This research study is exploring a new way to screen for colorectal cancer using DNA methylation technology — a method that looks at chemical changes in DNA found in stool samples. Instead of undergoing invasive procedures, participants would simply provide a stool sample that researchers analyze to see if this non-invasive approach can reliably detect colorectal cancer and precancerous growths (called adenomas) in people over 40. The goal is to develop a simple, at-home screening tool that could catch cancer early when it's easier to treat.

Colorectal cancer is a serious disease, but it's often preventable or more treatable when caught early. However, many people avoid screening because existing methods are uncomfortable or invasive. This study aims to solve that problem by creating an easier, non-invasive screening option using stool samples.
