I will tell you about the causes, symptoms, and prevention methods of lung cancer. This is a story about things that lung cancer patients should absolutely avoid, but even if you are not a lung cancer patient, it is very important to be aware of these things, as it can help you prevent lung cancer, so please remember and practice it.

1. Smoking

The first is smoking. Cigarettes contain over 400 toxic substances. Especially, nicotine, carbon monoxide, and tar, which are fatal to the lungs. These substances can increase the risk of cancer just by touching the lungs. The best way to reduce the risk of lung cancer is to avoid direct and indirect smoking.
 
It is generally known that 85% of lung cancer is caused by smoking and that smoking increases the risk of lung cancer by 13 times. The moment you quit smoking, the damaged lung tissue starts to heal itself gradually. Quitting smoking can significantly lower the risk of developing lung cancer.

2. Fine dust

Fine dust can pose a fatal risk to the lungs. Especially, fine dust in bad air is much worse. This fine dust is so small that it cannot be defended by the nose or tonsils. Such small fine dust enters the lungs and sticks to it, causing lung inflammation.
 
If this lung inflammation increases, the lungs cannot function properly and the risk of lung cancer being triggered is very high. It is said that fine dust is 9 times more dangerous indoors than outdoors. Therefore, it would be helpful to ventilate frequently indoors and use a good air purifier.
3. Cooking habits
It is said that 87.6% of female lung cancer patients did not smoke. Among them, if you do not ventilate while cooking in the kitchen or if you do not turn on the range hood, the risk of lung cancer is increased by up to 5 times. In particular, when using oil for frying or attaching dishes, you must ventilate. It is better to turn on the range hood 5 minutes before cooking, not while cooking.

4. Smartphone

The fourth is smartphones. It is not the smartphone itself that is the problem, but the posture of using it. When using a smartphone, you often take a posture where you bend your shoulders or back. In this case, the lung space is narrowed by about 20% and the amount of oxygen stored in the lungs decreases, threatening not only the lungs but also the overall health.

5. Alcohol

Alcohol is a cause of liver cancer, but it can also cause lung cancer. Women who drink alcohol two to three times a week or more have a 24.7% higher risk of developing lung cancer than women who drink less than three times a week. It is said to be more dangerous in general.

6. Ventilation

There are many cases where people avoid ventilation due to fine dust and air pollution, but it is good to ventilate even on days when fine dust is severe, especially when cleaning. The level of fine dust in an ordinary household is about 40, but it increases to 2090 when using a vacuum cleaner.
 
This tells us that it is much higher than the very bad level of fine dust. Therefore, if you have used a mop or vacuum cleaner, ventilate for 3-5 minutes if there is a lot of fine dust.

7. Breathing through the mouth

If you breathe through your mouth instead of your nose, more than 1,000 toxins that are not filtered through your nose enter your body directly. These toxins can be much more dangerous than cigarettes, especially bacteria, viruses, and bacteria in the air enter the body through the mouth.

8. Eating food in a hurry

Eating quickly is not good for the health of the stomach, but it is also very bad for the lungs. When you eat food, the hood in your throat is lowered, allowing it to enter the esophagus, but when you breathe, the hood in your throat is opened upwards, allowing it to enter the lungs. This happens much more often, especially when eating food quickly. Food can enter the lungs instead of the esophagus, which can lead to aspiration pneumonia.

9. Habit of sleeping with dentures

Many elderly people sleep with their dentures because they are too lazy or forget. But sleeping with dentures can increase the risk of pneumonia by more than twice, according to a study.
 
Researchers at Nihon University in Japan conducted an experiment on 524 elderly people over 85 years of age who had symptoms of pneumonia or died of pneumonia. The results showed that the group sleeping with dentures had a risk of pneumonia 2 to 3 times higher.
 
Today, I hope you will carefully consider and put into practice the habits that you should avoid when you have lung cancer or if you want to prevent lung cancer.
