Note: Why do so many people get lung cancer? Besides smoking, there are these 4 reasons

There are many people in life who like to smoke, but also know that smoking is not good for health. What's wrong with it, I don't know. Smoking is the most common cause of lung cancer. Let's find out why it causes lung cancer.

Why does smoking cause lung cancer?

When cigarettes are burned, the smoke produced contains many carcinogenic substances, which have great harm to the human lungs. Especially among teens, the earlier they started smoking, the more likely they were to develop lung cancer. Many teens are exposed to cigarettes because they are curious during development. This is a relatively weak resistance for minors because their bodies are not fully developed. It is easier to absorb the harmful substances in cigarettes, and it is more harmful to the human body.

For long-term smokers, long-term smoking will cause great damage to the lungs, resulting in insufficient gas exchange in the lungs, red blood cells in the body cannot combine with enough oxygen, and harmful substances in cigarettes will adhere to the lungs. The lungs become black and then prone to lung cancer.

Therefore, the probability of lung cancer in regular smokers is significantly higher than that in non-smokers, and the treatment effect of smoking and lung cancer is more difficult than that of non-smoking.

What are the causes of lung cancer?

First Occupation and the Environment

With the rapid development of the environment, air pollution has become more and more serious, such as exhaust gas from some factories, vehicle exhaust and second-hand smoke. Long-term exposure to this environment will lead to the occurrence of lung cancer. Or some long-term demands of working in environments with poor air quality are also prone to lung cancer.

second genetic factor

Some genetic families or immunocompromised and endocrine dysfunction can lead to lung cancer.

Three lesions

Some lung cancer patients are simple lung diseases in the early stage. If they are not detected or treated in time, they will completely lead to disease and cancer.

Four emotions

Emotions are also one of the causes of cancer. Now many people have increased stress in their lives, making their emotions anxious and tense, causing endocrine disorders in the body for a long time, lowering resistance, and allowing cancer cells to be used.

Warm reminder, smoking is a main cause of lung cancer, but not the main reason, living environment, diet, etc. can lead to the occurrence of lung cancer. Therefore, smoking is only one of the reasons. Therefore, people who like to smoke should pay special attention, try to control the intake of cigarettes, and remember that smoking is harmful to health. Only by reducing smoking can reduce the incidence of lung cancer.
