Can we spot cancer before it starts? a massive study aims to find out

NCT ID NCT05463796

First seen Aug 17, 2026 · Last updated Aug 17, 2026

Summary

This study is building a large collection of blood, saliva, urine, stool, and tissue samples from people who are at increased risk of cancer, including those with genetic predispositions, survivors of childhood or adult cancer, or those with precancerous conditions. The goal is to identify early changes and risk factors that could predict cancer development. By tracking participants over time, researchers hope to find new markers for early detection and ways to intercept cancer before it becomes life-threatening.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Collection of biological samples (blood, saliva, urine, stool, tissue) for research
What this could lead to
If successful, this could lead to better ways to predict who will develop cancer and new strategies to stop it before it becomes serious.
What could go wrong
This is an observational study, so it won't directly test a treatment. It may take years to find useful markers, and the findings might not apply to everyone.
