Using gut bacteria patterns to screen for colorectal cancer

Researchers are developing a new screening tool based on the bacteria naturally found in your gut. Scientists have discovered that certain bacterial patterns may signal the presence of colorectal cancer or precancerous growths. This study will collect stool samples and medical information from over 1,200 people to see if analyzing these bacterial signatures can improve how doctors screen for colorectal cancer.

Current screening methods like the FIT test sometimes miss cancers or cause unnecessary follow-up procedures. Doctors need better tools to accurately identify who has colorectal cancer or dangerous polyps, and research suggests that gut bacteria patterns might provide that answer.
