Prostate cancer risk: could a simple blood test predict it?
NCT ID NCT03383016
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is looking at how things like diet, physical activity, and other lifestyle habits might affect a man's risk of getting prostate cancer. Researchers are studying more than 2000 men who are at higher risk to find biological markers in the blood that could help predict risk. The goal is to eventually use these markers to personalize prevention strategies, such as recommending specific diet or exercise changes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simple blood test that helps identify men at high risk for prostate cancer, allowing them to make lifestyle changes to lower that risk.
- What could go wrong
- This is an observational study, not a treatment trial. It may not find clear biomarkers, and any findings would need further validation before being used in practice.
