Cancer cells hate oxygen: why isn't this avenue explored more?
If oxygen is life, cancer cells have developed a survival instinct that runs counter to it: they avoid it. Nearly a century ago, biochemist Otto Warburg discovered that a 40% drop in the oxygen level of a tissue can turn a healthy cell cancerous in less than 48 hours. The so-called Warburg effect holds that malignant cells have hardly any antioxidant enzymes, making them vulnerable to the free radicals generated by intense oxygenation. Paradoxically, more than half of tumors cause local anemia, preventing the body's defenses from using that same oxygen to attack them.
Metastasis, according to this line of research, is an escape: hypoxic cells migrate to areas where they can breathe better. This is why therapies such as ozone therapy and hyperbaric chambers have gained trinc as complementary treatments. However, the conventional medical community views them with skepticism, and robust clinical trials are scarce.
At the same time, certain everyday habits align with this logic: a clove of garlic on an empty stomach, moringa or extra virgin olive oil are mentioned as antioxidant boosters, though without conclusive evidence. The debate swings between those who see oxygen as an underused tool and those who dismiss it as pseudoscience.
If science has known about the Warburg effect for decades, why aren't oxygen-based therapies part of standard treatment?
