Hyperbaric Oxygen Therapy (HBOT) is a supportive treatment used to help cancer patients recover from radiation damage, improve tissue healing, and support overall recovery during cancer care.
Most people don’t hear about Hyperbaric Oxygen Therapy for Cancer from their oncologist. They find it themselves, usually after radiation has left tissue that won’t heal, or after chemotherapy has taken more of a physical toll than anyone quite prepared them for. What it does is straightforward: pure oxygen delivered under pressure gets into damaged tissue at levels normal breathing can’t touch. Circulation improves. The body gets what it actually needs to repair rather than just survive.
Many cancer patients use hyperbaric therapy to:
- Improve healing after surgery
- Reduce radiation injury
- Improve oxygen delivery to tissues
- Support recovery during chemotherapy
People fly to Zephyrhills for this. That’s worth saying plainly. Since 2003, patients have come to our hyperbaric oxygen therapy clinic from New York, Toronto, Mexico City, San Juan, Bogota, and dozens of other cities across the US, Canada, the Caribbean, Mexico, Central America, and Latin America. Over 60,000 physician-supervised sessions were completed in that time. They don’t make the trip because Florida is a nice place to visit. They come because 25 years of real clinical experience with cancer patients is genuinely hard to find in one place.
Some arrive mid-treatment, using HBOT alongside active chemotherapy or radiation under their oncologist’s guidance. Others finished treatment a year ago and are still carrying the physical aftermath. Radiation damage that hasn’t healed. Fatigue that never fully lifted. Tissue that just isn’t recovering the way it should. Whatever the situation, we’ve almost certainly worked with patients in exactly that place before.
What Is Hyperbaric Oxygen Therapy (HBOT)?
The chamber climbs to between 2 and 3 ATA, two to three times normal atmospheric pressure. You breathe 100% pure medical-grade oxygen the whole time. At that pressure, oxygen doesn’t just attach to red blood cells the way it normally does. It dissolves directly into blood plasma, cerebrospinal fluid, and tissue fluid at concentrations that simply aren’t achievable any other way.
For cancer patients, what follows from that matters a lot. New blood vessels grow into areas that radiation destroyed. Stem and progenitor cells activate in bone marrow and start circulating. Chronic inflammation, the kind that persists long after treatment ends and keeps tissue from healing properly, starts to resolve. Cells that have been sitting in a damaged, oxygen-starved state begin actual repair rather than just maintaining.
About the equipment: our chambers are ASME PVHO-certified, monoplace and multiplace, running at genuine 3 ATA pressure with medical-grade oil-free compressors and 100% medical-grade oxygen. Soft-shell home chambers don’t reach those pressures. The biological effects described here don’t happen at 1.3 ATA. That distinction is not a technicality.
Two pieces of research matter most for anyone thinking seriously about this. An NIH-funded study by Thom et al. confirmed that HBOT significantly mobilizes stem and progenitor cells essential for tissue repair and immune recovery. Research by Feldemeier et al. established that HBOT does not accelerate the malignant process. That second finding is the one that changed how oncology teams worldwide approach this therapy. It’s the question almost every cancer patient asks first, and the answer in the literature is clear and consistent.
Potential Benefits of HBOT for Cancer Patients
Many cancer patients explore Hyperbaric Oxygen Therapy as part of their supportive care plan. Some potential benefits include:
Improved Tissue Healing
Radiation therapy can sometimes damage surrounding healthy tissues. HBOT helps increase oxygen supply to these tissues, which may support recovery and repair.
Reduced Radiation Side Effects
Hyperbaric Oxygen Therapy is commonly used to treat radiation-induced tissue damage, including wounds that are slow to heal after cancer treatments.
Enhanced Oxygen Delivery
Increased oxygen circulation helps improve blood flow and may assist the body’s natural healing processes.
Support for Wound Healing
HBOT can support healing in areas where tissue has been weakened due to surgery, radiation therapy, or reduced blood supply.
Improved Quality of Life
Many patients report improvements in energy levels, healing, and overall well-being during supportive HBOT treatment.

How Hyperbaric Oxygen Therapy Supports Cancer Patients
Elevates Tissue Oxygen
HBOT raises oxygen levels far beyond what breathing ambient air can achieve, creating an environment that can suppress hypoxic (oxygen-deprived) tumor activity.
Stimulates Stem Cells
NIH-backed research confirms HBOT promotes stem and progenitor cell production — supporting the body's capacity for repair and regeneration during and after cancer treatment.
Reduces Inflammation
HBOT significantly decreases systemic inflammation — a key factor in cancer progression and a common source of treatment-related side effects including radiation tissue damage.
Enhances Radiation Efficacy
Higher oxygen levels sensitize tumor cells to radiation therapy, potentially improving treatment outcomes when HBOT is used as an adjunct to radiotherapy.
Supports Post-Treatment Recovery
HBOT accelerates healing of radiation-damaged tissue (radiation necrosis), surgical wounds, and other treatment side effects — improving patient quality of life.
Boosts Immune Function
Increased oxygen tension enhances white blood cell activity and immune response, strengthening the body's natural defenses during a period when conventional therapies can suppress immunity.
