Is the mortality rate of lung cancer high? The four major causes of lung cancer need targeted prevention

Cancer poses a huge threat to human life and health. Among many cancers, lung cancer is characterized by the fastest increase in incidence and mortality. According to relevant data, about 2.2 million people were diagnosed with lung cancer worldwide last year, and the number of deaths from lung cancer reached 1.8 million. The actual data should be even higher than this. Lung cancer has directly become the second most common cancer and the most deadly, which seriously threatens human health. Therefore, we must remain vigilant against this disease, especially those in high-risk groups.

So what are the main causes of lung cancer?

1. Many years of smoking history

At present, tobacco is considered to be the biggest culprit for lung cancer. Existing studies have shown that compared with non-smokers, long-term heavy smokers are more likely to develop lung cancer. Lung cancer is related to the age at which one starts smoking. The younger the age of smoking, the higher the chance of developing lung cancer. Tobacco contains a variety of carcinogens, including nicotine, tar, etc. Smoking not only harms one's own body, but also affects other people in the same environment. No matter how many hands are exposed to smoke, it is harmful to the human body. After the carcinogens in tobacco enter human cells, they can damage the DNA in the cells, causing cell cancer and inducing lung cancer. And the more you smoke and the longer you smoke, the greater the chance of cancer.

2. Long-term exposure to oil smoke

Generally speaking, compared with men, there are fewer women who smoke, and the number of women who get sick should not be high, but this is not the case. Then why is lung cancer also more common among women in recent years? The culprit is oil smoke, which forms smoke that contains a carcinogen that can cause lung cancer. When exposed to an oil fume environment for a long time, the higher the amount of carcinogen inhaled, the greater the chance of getting the disease.

3. Family history of lung cancer

Many studies have shown that lung cancer has a certain genetic tendency and that the environment also affects lung cancer. If someone in a family is sick, then his relatives, who have the same genetic material and live in a similar environment, are more likely to be sick.

4. Air pollution

Modern society is highly dependent on fossil raw materials such as coal, oil and natural gas, especially developed countries. The demand for fossil raw materials is in all aspects of daily life. The combustion of fossil raw materials produces harmful substances. The harmful substances are not properly treated, but directly discharged into the atmosphere. The human body then allows the harmful substances to enter the body through breathing. This is why the incidence of lung cancer is higher in developed countries. However, the world is a whole, and harmful gases in developed countries may also affect other regions. Reducing air pollution is an urgent matter.

The mortality rate of lung cancer ranks first among all cancers. A large part of the reason is that many patients are already in the middle or late stage when they discover the disease. The treatment options for middle and late stage lung cancer are limited and the survival period is short. Early diagnosis and treatment of lung cancer is crucial, and we must seize the best time for treatment.
