Non-small cell lung cancer

Non-small cell lung cancer is a heterogeneous group of epithelial malignancies originating in the respiratory tract, predominantly affecting older adults and individuals with tobacco exposure or other environmental inhalant risks Representing approximately 85% of all primary lung cancers, it primarily encompasses adenocarcinoma, squamous cell carcinoma, and large cell carcinoma

Representing approximately 85% of all primary lung cancers, it primarily encompasses adenocarcinoma, squamous cell carcinoma, and large cell carcinoma Pathophysiologically, it arises from cumulative genetic and epigenetic alterations in bronchial or alveolar epithelial cells—often involving oncogenic driver mutations—which lead to unregulated proliferation, local airway and parenchymal invasion, and potential lymphatic or distant hematogenous metastasis Clinically, it typically manifests with pe...

Pathophysiologically, it arises from cumulative genetic and epigenetic alterations in bronchial or alveolar epithelial cells—often involving oncogenic driver mutations—which lead to unregulated proliferation, local airway and parenchymal invasion, and potential lymphatic or distant hematogenous metastasis Clinically, it typically manifests with persistent cough, dyspnea, hemoptysis, and chest pain, though early stages are frequently asymptomatic
