First seen Nov 21, 2025 · Last updated Jun 11, 2026 · Updated 24 times
Summary
This study looks at whether taking vitamin D before a light-based treatment (photodynamic therapy, or PDT) can help the immune system fight nonmelanoma skin cancer. About 54 adults scheduled for skin cancer surgery will take either vitamin D or a placebo for 6 days before one PDT session. Researchers will then compare immune markers in the removed tumor tissue to see if vitamin D makes a difference.
