- Economically emerging countries, particularly BRICS (Brazil, Russia, India, China, South Africa), contribute over half of the global cervical cancer (CC) burden.
- From 1992 to 2021, age-standardized incidence rates (ASIR) of CC in BRICS decreased by 5.5%, and mortality rates (ASMR) declined by 33.7%.
- Brazil showed continuous decreases in both CC incidence and mortality.
- India reduced CC incidence and mortality but saw worsening period effects post-2012.
- Russia and China had decreasing mortality but increasing incidence, with Russia showing unfavorable trends among young and middle-aged women.
- South Africa had the highest CC incidence (40.0 per 100,000 women) and mortality (21.3 per 100,000 women) in BRICS, with steep age-related increases.
- Despite overall declining trends, substantial heterogeneity exists across BRICS nations, requiring tailored public health interventions.
