How do socioeconomic factors influence cancer rates and outcomes globally? This study examines socioeconomic inequalities in cancer incidence and mortality using GLOBOCAN 2022 data, focusing on the Human Development Index (HDI) and major world economies to understand the complexities of cancer burden distribution. Using GLOBOCAN datasets, the research compares cancer cases and deaths across cancer types in 2022, with projections to 2050. Age-standardized rates (ASIRs/ASMRs) for prevalent cancers were analyzed across top economies and HDI regions. Key findings reveal that prostate cancer predominates in males in low, high, and very high HDI countries, while breast and cervical cancers are prevalent in females in low-to-medium HDI countries. Higher HDI correlates with increased lung and colorectal cancer incidence. This study underscores the need for tailored cancer prevention and control strategies, considering the interplay of socioeconomic factors and developmental stages. The patterns observed in China reflect a blend of developed and developing country characteristics, highlighting the importance of evidence-based, comprehensive approaches to address cancer effectively.
Published in the Chinese Medical Journal, this study is aligned with the journal's broad scope covering various aspects of medicine and public health. The analysis of cancer incidence and mortality patterns, with a focus on socioeconomic inequalities and trends within China, directly contributes to the journal's mission of disseminating research relevant to the Chinese medical community and global health challenges. The findings inform the development of targeted interventions and strategies for cancer prevention and control, enhancing the journal's value as a resource for medical professionals and policymakers.
