Hyperbaric Oxygen Therapy (HBOT) in Cancer: Which Tumors Benefit Most?
Introduction: Why Oxygen Matters in Cancer A thorough understanding of the problem is half of the solution —and in cancer, one of the most overlooked problems is tumor hypoxia (low oxygen levels inside tumors). Hypoxia isn’t just a byproduct of tumor growth. It actively drives: Treatment resistance Metastasis Immune suppression Aggressive tumor behavior At the center of this process is Hypoxia-inducible factor 1-alpha (HIF-1α), a master regulator that helps cancer cells adapt and survive under low-oxygen conditions. This is where hyperbaric oxygen therapy (HBOT) comes in. Credit (1) What Is HBOT and How Does It Work? Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen at elevated pressure, dramatically increasing oxygen delivery to tissues. Key anticancer mechanisms: Reverses tumor hypoxia Increases reactive oxygen species (ROS) → cancer cell stress Enhances radiotherapy effectiveness Improves drug penetration Reduces hypoxia-driven resistance...
