The staging of bronchial squamous carcinoma needs to be judged according to the tumor size, lymph nodes and distant metastasis. In clinic, bronchial lung cancer is divided into 4 stages, firstly, to judge the size of tumor growth of bronchial squamous carcinoma, T stage can be judged, N stage refers to observe the degree of lymph node metastasis, and M stage refers to the occurrence of distant metastasis of bronchial squamous carcinoma. Therefore, the staging of bronchial lung cancer needs to be based on CT, MRI and other examinations to determine the size of the mass, the degree of lymph node metastasis and distant metastasis, etc. Specific staging needs to be combined with pathological examination, and according to the specific disease staging to determine the treatment plan and decide whether it is able to be operated or not, etc. Clinically, bronchial squamous cancer can be staged into T stage. Clinically, bronchial squamous carcinoma has different degrees of differentiation, slow growth rate, and precancerous atypical hyperplasia often lasts for many years before it evolves into malignant tumor in situ, so it needs to be detected and diagnosed as early as possible. It is recommended to consult thoracic surgery or oncology department of regular hospitals for bronchial squamous carcinoma.
