    Abstract:

    Lung cancer is a serious pulmonary tumor, with exacerbation of chronic lung inflammation being a precursor to the development of lung cancer. Relevant animal models are widely used in experimental research, to gain a deeper understanding of the pathogenesis of lung cancer and to develop preventive treatment strategies. Induced lung cancer animal models are of particular importance for understanding the transition from chronic lung inflammation to lung cancer. Early intervention is crucial for the prevention and treatment of lung cancer. Here we review the recent literature regarding the inducing factors for lung cancer, including carcinogens ( e. g. nicotine-derived nitrosamine ketone, benzopyrene, diethylnirtosamine atmospheric fine particulate matter (PM2. 5 ), coal smoke, heavy metal ions,radiation, and biological infections ). We also summarize animal models of lung inflammation and cancer transformation induced by these factors, discuss the mechanisms by which relevant carcinogens induce lung cancer,analyze the advantages and limitations of the animal models, and consider future development directions. This review aims is to provide a valuable reference for the future establishment of relevant models.
