For many patients with advanced cancer, the greatest source of fear is not always the tumor itself. Rather, it is the feeling that their immune system is gradually collapsing—that their body can no longer protect them the way it once could. Even after standard treatments such as chemotherapy, radiotherapy, targeted therapy, or immunotherapy, many patients express the same worry: “My immune system feels too weak. What if the cancer comes back?”
For many cancer patients, the battle is not only against the tumor itself, but also against the physical toll of treatment. Even though intensity-modulated radiation therapy (IMRT) is more precise than traditional radiotherapy, its side effects—especially bone marrow suppression—remain a major challenge that affects patients’ safety, immunity, and overall quality of life.
For many nasopharyngeal cancer patients, the real challenge begins only after they are told the tumor has been successfully controlled and life is getting back on track. Although radiotherapy saves lives, its long-term sequelae—especially hearing loss and Eustachian tube dysfunction—often trouble patients for years, even more than a decade, leaving many survivors feeling they are still trapped in the shadow of the disease.
The process of cancer treatment is often long and arduous, especially when patients must undergo radiotherapy, which can lead to significant physical and emotional fatigue. For many liver cancer patients, surgery remains the most effective curative option. However, when the condition or physical status does not allow for surgery, radiotherapy and chemotherapy often become the primary choices. While radiotherapy can effectively kill cancer cells, it can also damage healthy tissues, leading to severe fatigue, nausea, loss of appetite, and a decline in overall quality of life during treatment.
For people living with advanced cancer, the goal of treatment is often not just survival but also comfort, dignity, and the ability to live meaningfully despite illness. Years of chemotherapy, radiotherapy, and medications can leave patients exhausted, sleepless, and in pain. Many begin searching for gentler approaches — treatments that not only extend life but also restore energy and ease suffering.
For patients diagnosed with advanced non-small cell lung cancer (NSCLC), the journey of treatment is often long and arduous. Many undergo chemotherapy, targeted therapy, or immunotherapy — essential options that can suppress tumor growth but also bring severe side effects such as nausea, fatigue, cough, breathing difficulty, rash, or liver toxicity. These complications can sometimes make the treatment feel more unbearable than the disease itself. For such patients, finding a safe, effective, and quality-of-life-oriented complementary therapy has become a shared wish.
With continuous advances in medical technology, cancer treatment is no longer limited to traditional surgery, radiotherapy, and chemotherapy. Increasing clinical and fundamental research suggests that the body’s internal balance and self-repair capabilities play a crucial role in the overall recovery process. Hydrogen therapy (H₂ therapy) is one of the emerging complementary options gaining attention under this trend.
In recent years, more and more cancer patients and their families have begun paying attention to the term “molecular hydrogen therapy.” Some people drink hydrogen-rich water, inhale hydrogen gas, or use hydrogen-generating devices, hoping to relieve the side effects of chemotherapy and radiotherapy and improve their overall physical condition and quality of life.
For patients diagnosed with colorectal cancer (CRC), surgery remains the first-line and most effective treatment. However, recurrence, metastasis, and the harsh side effects of chemotherapy often make recovery an uphill battle. The widely used chemotherapy drug 5-fluorouracil (5-FU) can cause nausea, fatigue, mouth ulcers, liver dysfunction, and weakened immunity. For many patients, enduring these side effects is sometimes harder than fighting the cancer itself.
