Scientists hunt for biomarkers to predict radiation damage

This study analyzed blood, urine, and tissue samples from 273 adults with brain or lung cancer who were receiving radiation therapy. The goal was to find biological markers that could predict which patients are more likely to develop serious side effects from radiation, such as lung inflammation or brain tissue damage. Researchers also looked for markers linked to overall survival. The study did not test any new treatment, but aimed to improve future care by identifying patients at higher risk.
