Apparently, the place where we live, more precisely the altitude above sea level on which we live is of great importance when lung cancer development is in question. In fact, the latest research has shown that people who live in lowlands have a greater risk of lung cancer development compared to those who live in the mountains.
By now, smog, genetics, smoking and working life spent in a mine, have been some of the reasons listed as the most common causes for lung cancer; but from now on we will also add this one reason to the list – the air we breathe! YES, it is the composition of air itself that has been the plain reason why people in certain areas throughout the world acquire lung cancer.
The air differs at different altitudes but “the percentage of oxygen is the same at sea level as it is at high altitudes, which is roughly 21 percent.” The difference consists in the dispersion of air molecules, which is greater at higher altitude, and thus “each breath delivers less oxygen to the body.” Therefore, the air in the lowlands is thicker and more oxygen is delivered to the body. Although oxygen is important for our existence and well-being, it also has a negative side.
This is so because we use oxygen in the process of digestion, or more precisely, in the transformation of food into energy, a process called oxidation. However, during this process, free radicals, which are extremely carcinogenic metabolic products, are released. You must have heard or read about how harmful free radicals can be to our organism and that they can damage our DNA and cause cell mutations, which eventually may lead to cancer development.
“Our lungs, being the first organs affected by oxygen, are most likely to develop cancer.”
Another American study has found that on every 100 meters of attitude above sea level, the risk of lung cancer development decreases multiple times.
In conclusion, if you really want to avoid or at least reduce the risk of developing lung cancer, you should consider moving to a higher altitude above sea. Thus, you will also improve the work of your lungs because it’s commonly known that they spread and work much better on fresh and unpolluted air.
