First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to find new markers in urine that can tell the difference between aggressive prostate cancer and slow-growing types that don't need treatment. Researchers will analyze urine samples from 2000 men before and after they take a multi-carotenoid supplement for 8 weeks. The goal is to improve screening and reduce overtreatment of harmless prostate cancers.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Multi-carotenoids (dietary supplement)
What this could lead to
If successful, this could lead to a simple urine test to better identify aggressive prostate cancers and avoid unnecessary treatment for harmless ones.
What could go wrong
This is an early-stage observational study, not a treatment trial. The urine markers may not prove accurate enough for clinical use, and the supplement part is small and short-term.
