Correct answer: C — low-level laser therapy for prevention and treatment of oral mucositis from radiotherapy ± chemotherapy for head and neck cancer
Low-level laser therapy (LLLT/photobiomodulation) has strong evidence from multiple RCTs and meta-analyses for preventing and treating oral mucositis from head and neck RT ± chemotherapy. It reduces mucositis severity, pain and functional impact. ESMO/MASCC 2024 guidelines give it the strongest recommendation grade for mucositis prevention. The mechanism involves anti-inflammatory and wound-healing promotion at the cellular level. It requires specialised equipment and trained staff, limiting availability.
