Non smoker, at this out!
First Invisible radioactivity
The main cause of lung cancer in nonsmokers is exposure to radon. He is in the environment occurs naturally in harmless amounts, in some areas, but its concentration is higher. It accumulates mainly in buildings built on land rich in uranium. Studies show that people who have long lived in areas with high concentrations of radon are at risk of lung cancer, although smoking. Radon can not be seen or smelled, so the only way to determine its concentration, the specific test your home.
Second "Smoking" environment
Even if you yourself do not ignite a cigarette, smokers are often exposed to harmful substances in cigarette smoke. While throughout the European Union, the trend of smoking in public places limited, Czech Republic in this regard is still lagging. This makes the fumes of tobacco exposed to small children.
3rd Carcinogens at work
Some jobs mean daily contact with carcinogenic substances, such as asbestos or exhaust gases. Safety conditions at work over the last few years have improved, but if you are working in a similar environment, try to limit exposure to these substances to a minimum.
4th Air pollution
The link between air pollution and lung cancer is not in doubt. In October 2013, classified the International Agency for Research on Cancer (part of the World Health Organization) air pollution as an independent risk factor for lung cancer.
5th Gene mutations
Scientists reveal more information about how to actually healthy cells from becoming cancer cells and the malignant cells are different in smokers and non-smokers. It shows that in non-smokers are more likely to present specific mutations in the genes that cause cancer. This mutation results in uncontrolled proliferation and growth of cells. This information contributes to the development of new targeted therapies that act just the mutated genes.
Select a life without tobacco
Smoking is still the most important risk factor for lung cancer. Men smokers are 23% more vulnerable to cancer than gentlemen without this habit. For women, the difference is 13%. As smokers have thus escaped the greatest danger of cancer. If you still have concerns, find out the amount of radon in your home and reduce passive smoking to a minimum.
