What are the six major causes of lung cancer? Read this article to understand clearly

Cancer has now become a topic that makes people turn pale at the mention of "cancer," and among these, lung cancer ranks firmly in first place in many cities. From this, one can also see how important it is to prevent and treat lung cancer, and the first step is to understand what causes lung cancer. In terms of the main causes, the causes of lung cancer are smoking, work and living environment, ionizing radiation, persistent lung infections, genetic factors, air pollution, and so on.

Smoking has a hundred harms and no benefits, which is something everyone knows, but in fact there are still plenty of smokers, and this may also be the reason why the number of lung cancer patients keeps rising today, because among the causes of lung cancer, the number one cause that remains high is smoking, and family members of people addicted to cigarettes have also become a high-risk group for lung cancer. Little do people know that a small cigarette contains 3000 kinds of chemical substances, and the aromatic hydrocarbon compounds in cigarettes, namely benzopyrene and nitrosamines, are both very strong carcinogens.

The onset characteristics of lung cancer also show an occupational trend, that is, about 10% of patients have environmental and occupational factors, and at present 9 types have been clearly identified: by-products of aluminum products, arsenic, asbestos, chloromethyl ether, chromium compounds, coke ovens, mustard gas, nickel-containing impurities, and vinyl chloride. In addition, frequent contact with substances such as beryllium, cadmium, silicon, and formalin can also increase the incidence of lung cancer. Finally, there is smog, industrial waste gas, and so on.

Next there are ionizing radiation, a past history of lung disease, and genetic factors. In fact, ionizing radiation, together with the previously mentioned causes that can lead to lung cancer, is also the cause of many lung diseases, and it is the long-term presence and development of lung diseases that is the direct factor in lung cancer. Ionizing radiation means that employees who have long been engaged in mining radioactive ore are prone to occupational lung cancer, with a probability of 70%-80%, and the most common type is squamous cell carcinoma.

Patients with squamous cell carcinoma may have a history of radioactive ore mining of 10 to 45 years, and the average age of onset for squamous cell carcinoma is 38 years old, so this is a notable point. There is also radon and its progeny, and not only mouse experiments but also the fact that the incidence of lung cancer among survivors of the atomic bombings in Japan rose significantly. Lung diseases causing lung cancer can almost be said to include tuberculosis, chronic bronchitis, bronchiectasis, and other diseases that spread and linger, all of which are pathogens of lung cancer.
