Summary
This pilot study at MD Anderson Cancer Center looks at how diet and the microbiome (gut bacteria) might cause changes in colon cells that could lead to colorectal cancer. Researchers will compare vegetarians and non-vegetarians undergoing screening colonoscopies. They will analyze diet, stool, blood, and colon tissue samples to find links between eating habits, gut bacteria, and early cell mutations.

What this could lead to
If successful, this study could reveal how diet and gut bacteria influence early changes that may lead to colon cancer, pointing toward future prevention strategies.
What could go wrong
This is a small, early pilot study (30 people) that only observes and measures, not tests a treatment. Results may not apply to everyone and may not directly lead to cancer prevention.
