What are the pathogenic factors related to lung cancer? To prevent lung cancer, these causes should be avoided

If you smoke 40 cigarettes a day, you will reach this risk index in 10 years. If the "smoking index" reaches 400 and you are over 40 years old, it is recommended to have a physical examination at least twice a year and a chest CT scan to check the health of your lungs. Because lung cancer generally takes only 3 to 6 months for the tumor to double in size, the development speed is very fast.

Nowadays, many people believe that smoking is the culprit of lung cancer. However, they do not know that there are many factors that can lead to the occurrence of lung cancer. Experts point out that, for example, floating pollutants, dust, and tuberculosis in the air can all lead to the occurrence of lung cancer. Patients must pay attention to the prevention of these risk factors.

In case of traffic jam, you need to use "internal circulation". Today, cars are entering families in large numbers. One thing that cannot be ignored is the damage that car exhaust can cause to the lungs. Especially during the rush hour in winter, if you encounter a traffic jam, the exhaust concentration in the "local area" is very high. At this time, car owners must not open the windows. The best way is to circulate the air in the car before driving, and use the ventilation device in the car for "internal circulation" in case of traffic jam. For cyclists or pedestrians, it is best to stay away from the "long queue of cars" and pass quickly.

Beware of radon pollution after home decoration. In recent years, there is another situation that has attracted the attention of industry insiders, that is, the indoor home decoration air pollution source that is easily overlooked by people - radon. Where does radon come from? Studies have confirmed that building materials are the main source of indoor radon, such as granite, brick sand, cement, tiles and gypsum, especially natural stones containing radioactive elements are prone to release radon. In addition, natural gas and coal gas will also produce radon after combustion.

Radon is non-volatile, and its concentration is related to factors such as the structure of the house and ventilation conditions. In winter, doors and windows are closed for a long time, and ventilation is less, so the concentration of indoor radon pollution is the highest, and people are more vulnerable to it. The World Health Organization has listed radon as one of the 19 major environmental carcinogens, so when living in a newly renovated house, you must open the windows frequently for ventilation.

A study of 400-year smokers who have physical examinations twice a year found that there is a risk index for smoking called 400-year cigarettes. This means that if you smoke 20 cigarettes a day for 20 years, the multiplication is 400.

If you smoke 40 cigarettes a day, you will reach this risk index in 10 years. If the "smoking index" reaches 400 and you are over 40 years old, it is recommended to have a physical examination at least twice a year and a chest CT scan to check the health of your lungs. Because lung cancer generally takes only 3 to 6 months for the tumor to double in size, the development speed is very fast.

According to data, there are more lung cancer patients in cities than those living in rural areas. From this, we can infer that the causes of lung cancer are closely related to urban pollution. Therefore, friends living in cities, if they have time, can travel to scenic places more often, which can improve their physical condition.
