Not oxygen alone.<\/dd>\n<\/dl>\n<\/div>\n<div class=\"rest\">\n<p>A tumor grows faster than its blood supply can keep up. It stimulates the formation of new blood vessels, but these become crooked, leaky, and unevenly distributed. Oxygen is scarce in the spaces between them \u2013 and in this state of oxygen deprivation, tumor cells do indeed become more problematic: they switch to fermentation, they become more mobile, and they respond less well to radiation. So far, everything you read about it is correct.<\/p>\n<h4>Where the ending tips over<\/h4>\n<p>The popular conclusion is: if oxygen deficiency strengthens the tumor, then more oxygen weakens it. But for this to work, the oxygen would have to reach the areas where it&#039;s lacking\u2014and that&#039;s precisely what it doesn&#039;t, because the blood vessels don&#039;t reach those areas. You can saturate the blood with oxygen until it can&#039;t anymore, and the oxygen-deprived areas within the tumor will remain oxygen-deprived. This isn&#039;t an argument against oxygen. It&#039;s the reason why everything that has truly been studied in this area takes place in a specific setting: under pressure, in a clinical environment, in conjunction with radiation therapy. That&#039;s what the next chapter is about.<\/p>\n<p>And one misunderstanding needs to be cleared up right here: <b>Cancer is not caused by a lack of oxygen.<\/b> The deficiency develops in the tumor after it has formed.

There are no studies on cancer. What some websites claim &quot;proven to increase mitochondrial function&quot; comes from these other contexts and from cell culture experiments.
