The link between oxygen and cancer is clear. In fact, an underlying cause of cancer is low cellular oxygenation levels.
In newly formed cells, low levels of oxygen damage respiration enzymes so that the cells cannot produce energy using oxygen. These cells can then turn cancerous.
In 1931 Dr. Warburg won his first Nobel Prize for proving cancer is caused by a lack of oxygen respiration in cells. He stated in an article titled "The Prime Cause and Prevention of Cancer...the cause of cancer is no longer a mystery, we know it occurs whenever any cell is denied 60% of its oxygen requirements..."
"Cancer, above all other diseases, has countless secondary causes. But, even for cancer, there is only one primary cause. Summarized in a few words, the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar. All normal body cells meet their energy needs by respiration of oxygen, whereas cancer cells meet their energy needs in great part by fermentation. All normal body cells are thus obligate aerobes, whereas all cancer cells are partial anaerobes."
Poor oxygenation comes from a buildup of carcinogens and other toxins within and around cells, which blocks and then damages the cellular oxygen respiration mechanism. Clumping up of red blood cells slows down the bloodstream, and restricts flow into capillaries. This also causes poor oxygenation.
Warburg and other scientists found that the respiratory enzymes in cells, which make energy aerobically using oxygen, die when cellular oxygen levels drop to.
When the mitochondrial enzymes get destroyed, they're host cell can no longer produce all its energy using oxygen. So, if the cell is to live, it must, to some degree, ferment sugar to produce energy. For a short period of time, like when running a race, this anaerobic fermentation of sugar is okay. Your legs build up lactic acid from this fermentation process and burn, and you stop running. Then your cells recover and produce energy using oxygen. However the problem comes when your cells cannot produce energy using oxygen because of this damage to the respiratory enzymes. Then they must produce energy primarily by fermentation most of the time. This is what can cause a cell to turn cancerous.
J. B. Kizer, a biochemist and physicist at Gungnir Research in Portsmith, Ohio explains, "Since Warburg's discovery, this difference in respiration has remained the most fundamental (and some say, only) physiological difference consistently found between normal and cancer cells. Using cell culture studies, I decided to examine the differential responses of normal and cancer cells to changes in the oxygen environment.
"I found that... "High 02 tensions were lethal to cancer tissue."
Low oxygen levels in cells may be a fundamental cause of cancer. There are several reasons cells become poorly oxygenated. An overload of toxins clogging up the cells, poor quality cell walls that don't allow nutrients into the cells, the lack of nutrients needed for respiration, poor circulation and perhaps even low levels of oxygen in the air we breathe.
Chemotherapy and radiation are used because cancer cells are weaker than normal cells and therefore may die first.
However, chemo and radiation damage respiratory enzymes in healthy cells, and overload them with toxins, so they become more likely to develop into cancer. The underlying cancer causing conditions are worsened, not improved. And the cancer usually returns quickly a second time unless you make changes to support the health of your body.
The implication of this research is that an effective way to support the body's fight against cancer would be to get as much oxygen as you can into healthy cells, and improving their ability to utilize oxygen. Raising the oxygen levels of normal cells would help prevent them from becoming cancerous.
And increasing oxygen levels in cancer cells to high levels could help kill those cancer cells.
