Text message reminder aims to boost cancer screening rates
NCT ID NCT07628998
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether sending a single SMS reminder to people who haven't completed a colorectal cancer screening test can increase participation. Over 10,000 adults aged 50-69 in Spain will be randomly assigned to receive either the SMS or standard postal reminders. The goal is to see if a simple text can help meet the recommended 65% screening target.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SMS text message reminder
- What this could lead to
- If it works, this could show that a simple text message can significantly increase colorectal cancer screening rates, helping catch cancer earlier.
- What could go wrong
- This is a behavioral study, not a medical treatment. The effect may be small or not apply to other regions. It only measures participation, not cancer outcomes.
