Background: Lung cancer is the most common cancer and a leading cause of cancer-related deaths globally. The aim of this study was to evaluate the incidence and mortality of lung cancer worldwide in 2022 and to project the number of new cases and deaths due to lung cancer in China and the United States in ***: In this study, data from the GLOBCAN 2022 database were used to analyze lung cancer incidence and mortality. The current status of lung cancer incidence and deaths was described by country/region, sex, age, and the human development index (HDI), and future lung cancer incidence and deaths in China and the United States were projected for ***: Globally, an estimated 2,480,675 new lung cancer cases and 1,817,469 lung cancer-related deaths occurred in 2022, with age-standardized incidence rates (ASIRs) and age-standardized mortality rates (ASMRs) of 23.6/100,000 and 16.8/100,000, respectively. In China, the ASIR and ASMR for male lung cancer patients were approximately 1.7 times and 2.7 times greater than those for female lung cancer patients, respectively. The ASIR and ASMR in high-HDI countries were approximately 8.5 times and 6.5 times those in low-HDI countries, respectively. It is estimated that in 2050, there will be approximately 1120 thousand new cases and 960 thousand deaths among Chinese men, 680 thousand new cases and 450 thousand deaths among Chinese women, approximately 170 thousand new cases and 110 thousand deaths among American men, and 160 thousand new cases and 90 thousand deaths among American ***: There are significant differences in the incidence and mortality of lung cancer among different regions and sexes. Therefore, sex factors need to be considered in the prevention, screening, and treatment strategies of lung cancer, and the implementation of tertiary prevention measures for lung cancer, especially primary and secondary prevention, needs to be actively promoted.
