Taiwanese women born after 1975 in cities and 1980 in rural areas show dramatically elevated cervical cancer risks compared to earlier generations, with urban women born in 1990 facing 1.9-fold higher rates than those born in 1975. Rural women from the 1990 birth cohort experienced 1.4-fold increased risk versus their 1980-born peers. This generational reversal occurred despite Taiwan's comprehensive cytology screening program launched in 1995, which successfully reduced overall incidence rates through 2019. The cohort-based analysis suggests behavioral and environmental shifts may be driving these concerning patterns. Sexual behavior changes and urbanization likely contribute to increased HPV exposure among younger generations, potentially overwhelming protective effects of screening programs that primarily detect precancerous lesions rather than prevent initial infection. This Taiwanese data mirrors troubling patterns observed in other developed nations where cervical cancer rates are climbing among millennials and Gen Z women. The findings underscore limitations of screening-only approaches and highlight the critical importance of primary prevention through HPV vaccination. For younger women, the data suggests current prevention strategies require recalibration to address evolving risk factors while maintaining screening compliance.
