There is no benign central lung cancer. Lung cancer refers to malignant tumors originating from the bronchial epithelium or alveolar epithelium. There are various classifications of lung cancer, which can be classified into central lung cancer and peripheral lung cancer according to the site of occurrence, and non-small cell lung cancer (including squamous carcinoma and adenocarcinoma) and small cell carcinoma according to the type of pathology. Since lung cancer is a malignant tumor, it is a malignant tumor regardless of its type, including central type lung cancer. Although lung cancer is a malignant tumor, early detection and active treatment can significantly prolong life, such as early squamous lung cancer and adenocarcinoma of lung, which can be cured with surgical treatment and significantly improve the five-year survival rate, so patients are advised not to be overly panicked, early detection, early treatment, and scientific treatment of cancer.
