Hyperbaric oxygen therapy (HBOT) involves breathing enriched oxygen in a pressurized chamber, which increases oxygen delivery to tissues and cells.
Whilst not a direct treatment for cancer, it is sometimes considered as an adjunctive therapy for cancer patients due to several potential benefits:
Enhanced radio and chemo therapy efficacy.
High oxygen levels can make cancer cells more susceptible to radiation damage, improving the effectiveness of radiation therapy.
Reduces Hypoxia. Tumours often have low oxygen (hypoxia), which makes them resistant to radiation. HBOT may counteract this resistance.
Wound Healing & Post-Surgical Recovery
- Helps heal **radiation-induced tissue damage (e.g., osteoradionecrosis, radiation proctitis).
- Improves recovery after reconstructive surgery (e.g., flap/graft survival in cancer patients).
Can help reduce side effects of conventional Cancer Treatments.
- May reduce lymphedema (swelling due to lymph node damage).
- Helps with radiation cystitis** (bladder inflammation) and **radiation enteritis** (intestinal damage).
Potential Anti-Cancer Effects (Theoretical & Controversial)
- Some preclinical studies suggest high oxygen levels may slow the growth of certain cancers, but evidence is limited.
Improved Quality of Life
- May reduce fatigue, improve healing, and enhance overall well-being in cancer patients.
**Cautions & Considerations**
Not a standalone cancer treatment, should be used alongside conventional therapies.
**Conclusion**
HBOT is primarily used in cancer care to support radiation therapy and manage complications, not to treat cancer directly. Patients should discuss risks/benefits with their oncologist before considering HBOT.
