What causes lung cancer? The four major causes of lung cancer are better if you know them early

Lungs are very important to us, and they are an indispensable part of our respiratory system. However, due to various reasons in daily life, lung diseases and even lung cancer may occur. So what are the causes of lung cancer? Today, experts will explain to you several causes of lung cancer.

Reason 1: Smoking.

A large number of investigations and studies have proven that smoking may be one of the main culprits of lung cancer. In the legend of the relevant statistical department, the growth curve of lung cancer has the same trend as the sales curve of cigarettes. From the composition of cigarettes, it contains benzopyrene, which is a high carcinogen. In addition, there are some other carcinogens.

Researchers have conducted experiments on animals and proved that cigarette smoke can cause cancer in the respiratory tract and skin of mice after being inhaled. Surveys also show that the incidence of lung cancer in people who smoke is more than ten times higher than that of non-smokers. The incidence is even higher for those who smoke more heavily. This number is really shocking.

Reason 2: Air pollution.

A survey shows that the incidence of lung cancer in developed Western countries is significantly higher than that in developing countries. Moreover, the incidence of urban populations is also higher than that in other remote areas. The main reason is that industrial development emits a large amount of waste gas. For example, oil companies, refineries, coal combustion, etc. produce a large amount of harmful substances, which seriously pollute the originally clean sky. Nowadays, industrial development is getting faster and faster, and accordingly, the environment on which we depend for survival is also facing severe challenges. If we do not pay attention to environmental governance now and give the earth a blue sky, it will be too late to regret when we suffer environmental penalties.

Reason three: occupational influence.

The media once reported that there was a large-scale outbreak of lung cancer in some mining areas in Europe in the 1930s and 1940s. Since then, local authorities have begun to pay attention to it. Investigations have found that long-term exposure to radioactive substances such as tin, chromium, and arsenic in coal mines is an important cause of cancer. Today, the academic community has reached a consensus on this. In addition, substances such as asphalt, petroleum, and coal tar also have an inducing effect on the occurrence of cancer. Therefore, no matter which country, occupational disease prevention and control is highly valued.

Reason 4: Development of lung disease.

Many chronic lung diseases, if not treated in time, may develop into lung cancer after a long period of accumulation. Studies have also shown that the incidence of cancer in people with the above symptoms is higher than that of normal people. Chronic inflammation of the lungs and bronchi may lead to epithelial hyperplasia during treatment, and if it develops further, some of it may develop into lung cancer.

I believe everyone knows the above four diseases that induce lung cancer. For lung cancer, we should pay attention to prevention, do some aerobic exercise, and of course take good care of ourselves and develop good habits. If we do this, I believe that lung cancer will not be able to find a loophole to sneak into.
