NCT ID NCT07722442
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This pilot trial tests whether a personalised program called CANVIA can help adults aged 50 to 69 improve their diet and lifestyle habits in line with cancer prevention recommendations. Participants from breast and colorectal cancer screening programs in Spain are randomly assigned to receive a personalised report, the CANVIA mobile app, or the app plus health professional support. The study measures feasibility, usability, and early signs of behaviour change over six months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a personalised behavioural intervention using a mobile app and optional health professional support, based on WCRF/AICR cancer prevention recommendations
- What this could lead to
- If successful, this could point toward a scalable, personalised digital tool to help people adopt healthier habits that may reduce cancer risk.
- What could go wrong
- This is a small pilot study focused on feasibility, not proof of cancer prevention. The app's impact on long-term health outcomes remains unknown, and digital interventions often face low engagement.
