New laser blood test aims to detect breast cancer earlier

NCT ID NCT04273542

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This large study is testing whether a new laser-based blood test can help screen for breast cancer. Researchers will compare blood samples from women with and without breast cancer to see if the test can accurately spot the disease. If it works, it could offer a less invasive way to screen for breast cancer alongside mammograms.
