Therefore, it is imperative to investigate cancer incidence, mortality rates, and disability-adjusted life years (DALYs) to enhance preventive measures and healthcare resource allocation. This study aimed to assess cancer burden and associated risk factors in 204 countries and territories between 1980 and 2021.  \nMethods We selected data on cancer incidence and mortality rates and associated risk factors from the global burden of disease (GBD) study tool for 204 countries and territories from 1990 to 2021 and 1980 to 2021. We estimated the agestandardized incidence (ASIR) and age-standardized deaths (ASDR) of 34 cancer types categorized as level 3 causes based on the GBD hierarchy.  \nResults In 2021, cancer accounted for 14.57%(95% uncertainty interval: 13.65–15.28) of total deaths and 8.8%(7.99–9.67) of total DALYs in both sexes globally. ASIR and ASDR were 790.33 (694.43–893.01) and 116.49 (107.28–124.69), respectively. Additionally, females exhibited higher ASIR than males (923.44 versus 673.09), while males exhibited higher ASDR than females (145.69 versus 93.60). This indicates that policymakers should focus on the importance of gender equality in healthcare. Non-melanoma skin cancer exhibited the highest ASIR (74. 10) in both sexes, while digestive cancers accounted for 39.29% of all cancer-related deaths, and Asia exhibited the heaviest cancer burden. In females, breast cancer exhibited the highest ASIR (46.40) and ASDR (14.55). In males, tracheal, bronchial, and lung cancer exhibited the highest ASIR (37.85) and ASDR (34.32), highlighting the urgent need for targeted tobacco control measures. Different cancers in various countries exhibit unique characteristics. Therefore, policymakers should formulate specific prevention and control strategies that reflect the cancer in their country. Tobacco was the primary level 2 risk factor for cancer DALYs in males. It accounted for 29.32%(25.32–33.14) of all cancer DALYs. Dietary risks, alcohol consumption, and air pollution accounted for 5.89%(2.01–10.73), 5.48%(4.83–6. 11), and 4.30%(2.77–5.95) of male cancer DALYs, respectively. Therefore, policymakers should prioritize smoking regulation and other carcinogenic risks.  \nConclusion Cancer is a significant public health concern globally. Understanding the common etiologies of different cancers is essential for developing effective control strategies and targeted interventions.  \nKeywords Cancer, Global, GBD, Incidence, Mortality  \n*Correspondence: ZenghongWu [xhfive@hust.edu.cn](xhfive@hust.edu.cn)[ ](xhfive@hust.edu.cn)Rong Lin [linrong@hust.edu.cn](linrong@hust.edu.cn)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2024.
