Maybe you've heard of people who don't smoke but have lung cancer. Can this happen? In fact, besides smoking there are a number of other factors that can increase a person's risk of lung cancer.
Smoking is the most common cause of lung cancer. But not all cases of lung cancer occur in active smokers. To avoid this disease, you should know the cause of lung cancer in people who don't smoke.
Various Causes of Lung Cancer in People Who Don't Smoke
Here are some things that can be causes and risk factors for people who don't smoke but get lung cancer:
1. Exposed to radon gas exposure
Radon gas exposure is known to be a cause of lung cancer in nonsmokers. Radon gas is naturally present in the air and is generally harmless. Even so, the level or concentration of radon gas can increase in homes built on land containing natural uranium deposits.
In one study, it was found that the risk of developing lung cancer was higher in people who lived for years in radon-contaminated environments.
2. Too often become passive smokers
Too often inhaling secondhand smoke, for example due to living in a house with an active smoker or working in a smoker's environment, can also cause lung cancer. The reason, cigarette smoke has a number of substances that are carcinogenic and can damage lung tissue.
3. Exposed to asbestos exposure
Exposure to asbestos can also increase a person's risk of developing lung cancer. This is because asbestos fibers that are inhaled into the body can survive in the lung tissue for a long time. This is very dangerous, so the use of asbestos in the industrial field has been restricted and even banned in several countries.
4. Exposed to air pollution
For a long time, air pollution has contributed to the occurrence of lung cancer. Even the World Health Organization (WHO) has determined the types of outdoor air pollution, such as vehicle exhaust gases, wood stoves, and coal-fired power plants, as carcinogenic materials.
5. There are genetic factors (heredity)
Genetic factors play a role in increasing one's chances of developing lung cancer. Having a parent or family member suffering from lung cancer can increase your risk of developing lung cancer.
6. Gene mutations occur
Gene mutations can cause changes in the nature of lung cells become malignant. This is also a cause of lung cancer.
So, even if you are not an active smoker, the risk of developing lung cancer still exists. The things mentioned above are some of the causes and risk factors for lung cancer in nonsmokers.
As much as possible avoid these things and apply a healthy lifestyle. You are also advised to regularly check with your doctor to find out the health condition of your lungs.
