Photobiomodulation for the Management of Oral Mucositis in Cancer Patients

This review discusses the role of photobiomodulation (PBM) in preventing and managing oral mucositis, a painful and common side effect of chemotherapy and radiotherapy in cancer patients. Oral mucositis can lead to ulcers, inflammation, pain, difficulty eating, and increased infection risk. The article highlights PBM as a non-invasive supportive therapy that may reduce tissue damage, improve healing, and enhance quality of life during cancer treatment.

Key points:

• Reduces severity of oral mucositis – PBM may help decrease ulcer formation, inflammation, and tissue injury caused by cancer therapies.
• Pain relief – It can reduce oral pain and improve comfort for patients undergoing treatment.
• Promotes tissue repair – PBM may stimulate cell proliferation, collagen production, and healing of damaged mucosal tissues.
• Anti-inflammatory effects – Light therapy can modulate inflammatory pathways and reduce oxidative stress.
• Improves quality of life – By reducing pain and improving oral function, PBM may help with eating, speaking, and overall treatment tolerance.
• Clinical evidence – Several studies support PBM as an effective supportive therapy in oncology care, especially for prevention and symptom management.
• Safety and protocols – PBM is generally safe, but treatment success depends on correct wavelength, energy density, and standardized clinical protocols.

Simple takeaway:
Photobiomodulation is a promising non-invasive therapy for preventing and managing oral mucositis in cancer patients by reducing pain, inflammation, and tissue damage while promoting healing and improving treatment comfort.
