Can a website and text messages help colon cancer survivors eat better?
NCT ID NCT02965521
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a 12-week web-based diet program with text messages for 50 colorectal cancer survivors. The goal was to see if survivors would use the program and if it could help them eat healthier. The study did not test whether the diet changes actually prevent cancer from coming back.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- website and text messages
- What this could lead to
- If successful, this could lead to a larger study testing whether a web-based diet program helps colorectal cancer survivors eat healthier and potentially lower their risk of recurrence.
- What could go wrong
- This is a small pilot study (50 people) focused on feasibility, not on proving health outcomes. The results may not apply to all survivors, and the diet changes may not be enough to affect cancer recurrence.
