We aimed to explore the epidemiological characteristics and changes of lung cancer and the clinical medication in England from 2001 to 2019. We searched related research using search engine systems such as MEDLINE, PubMed, and PsychINFO. Lung cancer is a serious disease and the prognosis is usually very poor. The overall mortality rate of lung cancer decreased year by year in England from 2001 to 2019, but men, the elderly, and people exposed to polluted air are still more likely to be infected with lung cancer or die as a result, the prevalence and mortality rate of lung cancer in the north of England is significantly higher than that in the south, and the gap is increasing year by year. Lung cancer has changeable risk factors such as quitting smoking and improving air quality, which can effectively reduce the related risk. Paclitaxel, docetaxel, gemcitabine, and vinorelbine are the main drugs for the treatment of lung cancer in England and the treatment of these drugs is beneficial to the survival and quality of life of patients. Men and the elderly are at high risk of lung cancer, which means that lung cancer has obvious gender inequality and age inequality. At the same time, based on the statistical data of lung cancer risk in different regions, it can be concluded that lung cancer also has strong geographical and economic inequality. Changing risk factors and using drugs can effectively reduce the risk of lung cancer and provide effective treatment.
