Also, why in your opinion does the Buteyko methode (voluntary hypoventilation) seem to be such an effective treatment for asthma and similar conditions? And why does almost every cancer phenotype include hypocapnia and reduced oxygen use?
"It is known that the oxygen partial pressure in malignant tumors is lower than in unaffected tissue or in benign tumors [1, 2]. It is also established that the decreased partial pressure of oxygen stimulates cell proliferation [3]. The majority of researchers link tumor hypoxia to, first of all, the state of oxyhemoglobin in red blood cells. During the growth of malignant tumors, hyperventilation is developed, the partial pressure of blood carbon dioxide is lowered, and there is a shift of the curve of blood hemoglobin dissociation [4-6]. The degree of affinity of oxygen to hemoglobin decreases in accordance with tumor growth [7]. Moreover, the outer respiration function is disturbed: many patients with cancer have an increased minute ventilation which results in, on the one hand, reduced oxygen utilization, and, on the other hand, the development of hypocapnia. The reduced difference between the maximum lung ventilation and the minute ventilation increases the risk of metastasis [8]. It is also known that carbon dioxide improves tissue oxygenation, reduces lipid peroxide oxidation, and increases tissue tolerance to hypoxia [9]. Elimination of deep breathing promotes the elimination of hypocapnia [10,11]. It has been previously established that normal breathing improves the quality of life in patients with malignant tumors and increases the efficiency of special anti-cancer treatment. To normalize one’s breathing, the yoga methods of treatment have been used and their application resulted in a positive clinical effect [12, 13]. One of the preventive methods to reduce the recurrence and metastasis of breast and lung cancer is autogenic training which promotes the relaxation of skeletal muscles and breathing normalization [14]. Physical exercise is an important factor in normalizing the carbon dioxide concentration in lung alveoli in animals with experimentally induced tumors, and in patients with cancer. It can modulate the oxygenation of tumors and the parameters of metabolism and cellular immunity [15-17]."
Puschenko (2001): STUDY OF APPLICATION OF THE SHALLOW BREATHING METHOD IN A COMBINED TREATMENT OF BREAST CANCER
Cancer is unique because it has many strategies to manipulate the local extracellular pH. I think it's also very stupid to say that every cancer has these features. Different cancers vary in their pH. Some have more intracellular acidity and others are more alkaline. This will obviously determine how they manipulate their surrounding environment. Many people have studied this, and I don't have the time right now to go in depth with this. Gbolduev was right when he said this takes up too much personal time!
