Does CT lung shadow mean lung cancer? How should lung cancer be checked?

Lung cancer is one of the malignant tumors that endangers human life and health. It has a high incidence and mortality rate. The incidence rate of men is much higher than that of women, which is related to the fact that men smoke more. Pollutants in the atmosphere also contain carcinogens, and long-term inhalation can also induce lung cancer. Therefore, we should pay attention to avoid these inducing factors in our lives.

In recent years, the incidence of lung cancer has been increasing, and more and more people are suffering from the disease. The mortality rate of lung cancer is very high, so lung cancer is one of the malignant tumors that poses a serious threat to human health. Long-term studies have found that people with a long history of smoking are more likely to develop lung cancer, mainly because tobacco contains a lot of chemical substances, some of which have strong carcinogenic activity and can cause cells to become cancerous, such as nitrite and benzopyrene. Smoking is a high-risk factor for lung cancer. In addition to direct smoking, inhaling secondhand smoke is equally harmful to the body. For the sake of everyone's health, it is recommended not to smoke.

Smoking is only one of the factors that cause lung cancer. There are other reasons besides this. People with previous lung diseases, such as tuberculosis, bronchiectasis, etc., have a higher chance of developing lung cancer than ordinary people. The working environment can also be a factor that induces lung cancer. Working in an environment full of cadmium, silicon, arsenic, asbestos and other substances for a long time will increase the incidence of lung cancer. Air pollution can also affect people's lungs. Long-term inhalation of harmful substances in the air will promote the occurrence of lung cancer. Lung cancer is hard to prevent. You must pay more attention to it in your daily life and develop the habit of regular physical examinations to achieve early detection and early treatment.

There are many tests for lung cancer, including X-rays, which can give a general idea of ​​the location and size of the lung cancer, and can also check whether the adjacent parts are affected. Bronchoscopy can be performed to check the lesions of the bronchial lining and cavity, and to clearly diagnose the histological type. Sputum cytology can also be performed, which is a simple and effective method for screening and diagnosing lung cancer.

Typical lung cancer can be clearly diagnosed through examination. Sometimes it needs to be differentiated from some diseases, such as tuberculosis, benign lung tumors, and malignant mediastinal lymphoma. Only the most clear diagnosis can be beneficial to the treatment of lung cancer. The first choice of treatment for lung cancer is surgical treatment, which is also the only curative method. In addition, chemotherapy and radiotherapy can also be selected for the treatment of lung cancer.
