Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.
