It’s been long known that smoking is the main cause for one of the most difficult types of cancer – lung cancer. But, as it turns out there are other factors that play a key role in developing lung cancer, such as:
- Previous cancer treatment
- Low immunity
- Passive smoking
- Air pollution
- Lung disease
- Radon gas exposure
- Exposure to certain chemicals
- Family history of lung cancer
Researchers from a recent study linked lung cancer to altitude. Namely, the risk decreases multifold every 1000 meter of altitude, meaning that people who live in urban areas such as cities are more exposed to it than those who live in country or on mountain.
The reason lies in the air. The air in lowlands is denser with oxygen, which for some may not seem like a problem because oxygen is good, right? Well, not really. In fact, high oxygen concentration can cause a lot of damage.
Here is why: the body uses oxygen during digestion and turns food into energy – the process of oxidation. It can damage the cellular proteins and DNA because it is metabolized and creates free radicals. Those free radicals are the ones which trigger many diseases.
The air on a higher altitude is much healthier. By inhaling less dangerous oxygen you will reduce the risk of developing lung cancer.
