 The study aims to predict the future incidents of lung cancer in 40 countries by 2035, with an emphasis on country and sex-specific disparities. The results show that global ASRs of the 40 studied countries are predicted to decrease among males and increase among females, with peaks occurring in different regions and countries. The number of new cases is also projected to increase significantly by 2035. The study highlights the need for resource redistribution and improved LC control measures to reduce future LC burden worldwide.
