Background
The lung cancer, also known as bronchogenic carcinoma, is one of the most common malignant tumors in the world at present, the incidence rate has a significant increasing trend in most countries, the harm of the lung cancer is reflected in the continuously increasing incidence rate and mortality rate, the incidence rate of the lung cancer in China is a significant increasing trend at present, and the lung cancer is one of the leading causes of death of urban and rural residents in China and seriously threatens the health of people in China. Therefore, the control of lung cancer has become a problem of wide concern all over the world, the research on epidemiological characteristics of lung cancer and related general concerns thereof has positive significance on improving the tertiary prevention level of lung cancer.
The clinical manifestations of lung cancer are complex, with symptoms and signs being present, mild and severe, and the morning and evening of the appearance, depending on the site of the tumor, the type of pathology, the presence or absence of metastasis and complications, and the differences in the extent of response and tolerance of the patients. The staged diagnosis of lung cancer plays a guiding decision for the treatment of patients, the early symptoms of lung cancer are usually mild and even can be free of any discomfort, the central lung cancer symptoms appear early and severe, and the peripheral lung cancer symptoms appear late and mild and even are asymptomatic and are usually found during physical examination. The diagnosis is made through clinical symptoms, physical signs, imaging examination and histopathological examination, so the early diagnosis of the lung cancer has important significance, and better curative effect can be obtained only by diagnosing and treating the early stage of pathological changes. The lung cancer treatment method has the advantages that the lung cancer treatment method is vital to the treatment of lung cancer through three measures including surgical measures, chemotherapy and treatment, and the early lung cancer can be completely resected with pathological changes through the surgical measures according to the positions and the ranges of tumor invasion and the general conditions of patients, particularly the cardiopulmonary function storage condition, so that the survival purpose is achieved; more advanced lung cancer patients strive to remove the primary cancer tumor surgically, remove the metastatic lymph nodes as much as possible, and be assisted by radiation and chemotherapy, among other treatments.
In the clinical treatment process, the nature of the tumor needs to be judged by testing and pathologically evaluating the tumor tissue, and finally the nature of the pathological changes is determined, so that a basis is provided for the treatment decision of a clinician.
