HYPERBARIC OXYGEN THERAPY

Gentle, Oxygen-Rich Healing Support During Cancer

A calm, doctor-supervised way to help your body recover, repair and regain energy.

Support Your Recovery, Naturally

Hyperbaric Oxygen Therapy (HBOT) involves lying in a pressurised chamber and breathing in concentrated oxygen. It’s gentle, non-invasive, and used around the world to support healing, especially after surgery, radiation, or during cancer recovery. While not a treatment for cancer, it can support your body through treatment and beyond — by enhancing oxygen delivery to cells, promoting tissue repair, and reducing inflammation and fatigue.

Why You Might Use HBOT

When you’re facing cancer, you want every possible tool to support your healing. HBOT isn’t a magic bullet but for many, it’s a powerful complement to medical care. Here’s why:

  1. You feel exhausted, foggy or flat.
    Oxygen therapy helps increase cellular energy, reduce fatigue, and support clearer thinking when your body is under stress.

  2. You’re recovering from chemotherapy, radiation or surgery.
    HBOT supports faster healing by increasing blood flow and oxygen to damaged tissues - especially helpful for post-surgical wounds or radiation-induced fatigue.

  3. You’re dealing with inflammation, pain, or slow healing.
    By reducing swelling and boosting circulation, HBOT may ease nerve pain, joint discomfort, and help repair skin or tissue damage.

  4. You’re looking for natural, gentle support that doesn’t add more stress to your body.
    HBOT is non-invasive and deeply supportive, making it a safe companion therapy to help your body regenerate and rebalance over time.

Clinical Evidence & Research

Hyperbaric Oxygen Therapy (HBOT) is supported by a growing body of research in areas relevant to cancer recovery, including fatigue, immune regulation, radiation injury, inflammation, and tissue repair.

While HBOT is not a cure for cancer, it may play a valuable adjunctive role in supporting the body’s natural healing processes - especially when delivered under medical supervision, as it is through Cocoon.

  • HBOT helps increase oxygen levels in hypoxic tumor environments, making radiation and chemotherapy more effective. It’s also shown to reduce tumour resistance and support optimal treatment dosing by improving blood vessel function and oxygen delivery. Read more here

  • Studies indicate HBOT significantly alleviates radiation-induced tissue injury, promotes faster recovery from surgery through enhanced tissue repair, reduces infection risk, and eases lingering side effects - including “chemo-brain” fatigue. Read more here

  • Studies indicate HBOT helps alleviate post-chemotherapy fatigue and “chemo-brain,” improving mental clarity and overall wellbeing in breast cancer survivors. Read more here

  • Research shows that using HBOT alongside radiation boosts tumour oxygenation, which can increase radiation effectiveness, reduce tumour resistance, and support a stronger immune response. Read more here

  • HBOT enhances wound healing, reduces inflammation, and lowers infection risk, making it ideal for post-surgery recovery in cancer care. Read more here.

Real Support, Real Stories

  • "Made a MASSIVE difference to my recovery from major bowel surgery. I used it daily 3 weeks prior, and 4 weeks after my surgery. Was out of hospital in 2 days and no pain killers… When you have Cancer, you have to throw everything at it. Wish I’d known about Hyperbaric so much sooner. Very grateful."

    - Patient D -

  • “I was diagnosed with metastatic breast cancer… I leased a cocoon and spent daily sessions of 60–90 minutes … noticed a big difference in my ability to cope, pain was less, and other symptoms were easier to bear. What I found the most valuable… was Dr Gary’s support and genuine care.”

    - Patient I -

  • “I have been recently diagnosed with cancer… Dr Gary… had me set up with a Cocoon inside my home. I have been using it for 6 weeks to aid my general health and help prepare my body ahead of my Cancer treatment… I look forward to reporting how the Cocoon has assisted with my recovery once I carry out my cancer treatment and would not hesitate in recommending.”
