In the quest to improve cancer treatment results and boost patient well-being, an unexpected helper has emerged from the world of molecular elements—hydrogen gas. Hydrogen is set to revolutionise cancer care with its exceptional ability to act as a potential therapeutic agent and a promoter of general health. Here's a closer look at the cancer-specific research and its implications for patients and medical professionals.

The Dual Potential of Hydrogen in Cancer Treatment

Molecular Hydrogen's role in cancer treatment is multifaceted, exhibiting a capacity to induce or regulate apoptosis. This process can either lead to the death of harmful cancer cells or protect healthy cells from damage. Interestingly, hydrogen gas has the ability to adjust its role based on the cellular environment—acting as an inhibitor for pro-apoptotic proteins in some instances or as an enhancer of anti-apoptotic mechanisms in others. This dual potential offers a nuanced approach to targeting cancer cells while safeguarding normal ones, highlighting Hydrogen's versatility as a therapeutic agent.

Arresting the Cell Cycle

Research has shown that hydrogen gas can halt the proliferation of cancer cells by arresting their cycle at a critical phase, thereby inhibiting tumour growth. This effect is linked to Hydrogen's ability to regulate various cell cycle-related proteins, including Cyclin D1, CDK4, and CDK6, showing us another intriguing layer of its anti-cancer capabilities.

Immune System Modulation

Controlling malignant tumours' recurrence and spread is challenging due to factors like immuno-senescence and the gradual weakening of the immune system. Tumours can exhaust and deteriorate key immune cells, including T cells and natural killer cells, leading to increased regulatory T cells. Traditional treatments like surgery and chemotherapy can accelerate tumour spread. A 2019 study on 20 non-small cell lung cancer patients showed that two weeks of daily hydrogen inhalation significantly improved immune function, reducing exhausted T cells and increasing NK cells.

In 55 colorectal cancer patients, three months of hydrogen therapy reduced PD-1+ CD8+ T cells, associated with poor prognosis and improved outcomes. Hydrogen gas, combined with the immunotherapy drug Nivolumab, enhanced the effectiveness of exhausted CD8+ T cells in 42 lung cancer patients, leading to significantly longer survival compared to Nivolumab alone.

It also enhanced the effects of radiotherapy and chemotherapy by increasing the apoptosis rate in cancer cells. A case report described a non-small cell lung cancer patient who, after failing conventional treatments, experienced a reduction and eventual disappearance of brain metastases within a year of hydrogen gas treatment. This treatment also stabilised liver and lung metastases, extending survival.

Oxidative Stress and Inflammation Reduction

One of the most profound benefits of molecular Hydrogen is its selective antioxidant activity. Unlike other antioxidants, Hydrogen discriminates between harmful cytotoxic radicals and beneficial reactive oxygen species (ROS), reducing oxidative stress and inflammation without disrupting essential cellular functions. This specificity is particularly valuable in cancer treatment, where maintaining the balance of cellular processes is critical. 

High levels of Reactive Oxygen Species (ROS) play a significant role in the development and progression of cancer, negatively impacting patients undergoing treatments like chemotherapy and radiotherapy. Infections and exposure to fungal pathogens, chemicals, and pollutants exacerbate these levels. Elevated ROS can activate the PI3K/Akt/mTOR pathway, leading to apoptosis in non-cancerous cells and initiating a harmful cycle of toxic effects that may contribute to cancer recurrence and cachexia. In the case of ascites and ovarian cancer cells, increased expression of PGC1α is evident. It plays a significant role in chemoresistance as the process mediates the cells' response to oxidative stress. Hydrogen has been found to play a crucial part in regulating PGC1α expression. 

Hydrogen has shown the potential to counteract the downstream inflammation within the tumour microenvironment and in non-cancer cells impacted by aggressive treatment. It does this by minimising electron leakage in the electron transport chain, preventing the generation of superoxide in mitochondrial complex I, and correcting electron flow. This, in turn, reduces oxidative damage within the mitochondria of healthy cells.

Cancer patients must manage excessive systemic levels of ROS promptly, with guidance from an integrative health professional. Equally important is identifying and addressing the underlying causes and contributors of the excessive ROS with the guidance of a functional, naturopathic, or integrative health practitioner, ensuring a comprehensive approach to treatment and care.

Cancer Signalling Pathways

Hydrogen is emerging as a promising therapeutic agent by modulating cellular signalling pathways. Its influence on specific proteins and RNA, crucial in cancer progression, highlights its potential as part of comprehensive cancer care strategies. RNA sequencing analysis revealed hydrogen-induced TNF/NF-κB and apoptosis pathways in endometrial cancer cells. 

Hydrogen has been shown to reduce STAT3/Bcl2 signalling, promoting cancer cell death and encouraging autophagy. Furthermore, it suppresses the expression of the long non-coding RNA MALAT1 and the transcription factor EZH2, both implicated in the proliferation and migration of gastric cancer cells, further revealing its significant therapeutic promise.

Integrative Approaches to Cancer Therapy

In a comprehensive follow-up study, 82 cancer patients at stages III and IV underwent treatment through hydrogen inhalation, adhering to a "real world evidence" methodology over a period of 3 to 46 months. Remarkably, within the initial four weeks of treatment, participants experienced significant improvements in fatigue, insomnia, anorexia, and pain, indicating a positive response to the therapy. Their overall physical condition saw a notable enhancement of 41.5%, with lung cancer patients showing the most significant improvement, while those with pancreatic and gynecologic cancers experienced the least progress.

In cases where tumour markers were elevated—58 in total—a promising 36.2% displayed a reduction within 13 to 45 days, averaging at 23 days post-inhalation-treatment initiation. This effect was most pronounced in lung cancer patients, with pancreatic and hepatic cancer patients observing the least reduction.

Out of 80 patients with visible tumours on imaging scans, the overall disease control rate post-hydrogen inhalation treatment was 57.5%, including cases of complete and partial remission occurring between 21 and 80 days, with a median of 55 days. The disease control rate was significantly higher in stage III patients compared to those at stage IV.

This study underscores the potential of hydrogen inhalation at 3000ml/min as a therapeutic measure, especially for lung cancer, and opens avenues for further research into tailored treatments for different cancer types.


Beyond its direct anti-tumour actions, Hydrogen offers multiple benefits that address the side effects of conventional cancer treatments. From alleviating bone marrow damage to protecting the healthy cells of the gut, brain, kidneys, and liver during chemotherapy, hydrogen therapy supports patient health holistically. Research into its role in enhancing the outcomes of immunotherapy, in particular, emphasises the clear potential of Hydrogen as part of combination therapy regimens of the future.

Administration and Access to 3000 ml/min Hydrogen Machines

The versatility of Hydrogen extends to its administration methods, with drinking Hydrogen-rich water throughout the day being both safe and effective alongside Hydrogen inhalation being accessible and adaptable to various patient needs, including those diagnosed with lung cancer, where inhalation using a machine that produces 3000 ml/min has shown significant promise. At the time of writing this summary, the HAH machines are the only hospital-grade 3000 ml/min machines shipped worldwide directly to patients via FedEx and DHL.

The Path Ahead

The insights gleaned from ongoing research into molecular Hydrogen's role in cancer treatment are heartening. Hydrogen stands out as a potentially powerful tool in oncology because it offers a multifaceted approach that includes selective antioxidant activity, apoptosis regulation, cell cycle arrest, and modulation of cellular pathways.

Its capacity to mitigate the adverse effects of existing treatments while directly combating cancer cells opens the door to more refined and patient-friendly therapeutic strategies. Hydrogen therapy may become a cornerstone of future cancer care, embodying hope for patients worldwide.

Cancer patients and doctors are encouraged to explore this emerging therapeutic field, as hydrogen therapy represents not just a glimpse into the future of cancer care but a tangible, evolving reality with extraordinary potential.
