Oxygen promotes lung cancer

Can oxygen stimulate the air and is necessary for life, lung cancer?
Lung cancer mainly affects smokers, but 10 to 15% of cases include non-smokers. Other factors may already explain these conditions: genetic preparations, exposure to carcinogens such as particles and asbestos. Researchers say that the air we breathe often contains nitrogen and oxygen, but the presence of oxygen contributes to the formation of free radicals that damage cellular structures and cause DNA, and we may wonder if this oxygen is harmful to health. An increase in cancer cases has recently been observed in oxygenated children during the postpartum period.
To see if oxygen actually causes cancer, it is possible to compare the health of people living at different altitudes. . It is known that for the pressure observed at sea level, the oxygen level drops to 88.7% at 1000 meters, 78.5% at 2000 meters and 69.2% at 3000 meters.
In an article published in PeerJ, compare two researchers from the University of Pennsylvania and California cancer rates in 250 counties in the United States. Using data from the National Cancer Institute between 2005 and 2009. The researchers note that the incidence of lung cancer decreases by 7.23 cases per 100,000 people per 1,000 meters altitude. It has also been observed that the inverse relationship between height and lung cancer was very clear, taking into account both solar radiation and pollution, as these variables vary in height.
However, researchers have not observed this association with breast, prostate or bowel cancer. The role of the inhalation process Here, there is a need for a less carcinogenic carcinogen present at altitude, making the oxygen potentially responsible. The hypothesis of the researchers suggests that oxygen promotes the production of free radicals, which can stimulate the appearance of cancer.
