The costs of equipment, reagents, and the necessity for skilled personnel to perform and interpret these tests can lead to high per-patient expenses, making widespread adoption difficult. In resource-limited settings, the infrastructure for standard screening methods like Pap smears may already be inadequate, let alone the advanced technologies needed for genetic testing. Additionally, the cost-effectiveness of genetic screening is still under evaluation; implementing these advanced techniques may not always result in lower overall healthcare costs due to the potential need for follow-up procedures for positive or unclear results. Consequently, finding a balance between the benefits of early detection and the economic constraints of healthcare systems presents a significant challenge. 6.2 Ethical concerns in genetic screening The integration of genetic marker-based screening raises several ethical concerns, particularly related to privacy, consent, and the risk of genetic discrimination. Genetic testing can disclose sensitive information about an individual’s predisposition not only to cervical cancer but also to other hereditary conditions, prompting questions about how this information will be used and who has access to it (Wardle et al., 2015). Informed consent is critical, as individuals need to fully understand the implications of genetic testing, including the psychological effects of discovering an increased cancer risk and the associated anxiety. Moreover, there is a risk of genetic discrimination by employers or insurance companies, raising concerns about the confidentiality and security of genetic information. To address these issues, ethical guidelines and robust legal frameworks are necessary to protect individuals' rights and ensure responsible conduct in genetic screening. Tackling these ethical challenges is essential for the widespread acceptance and implementation of genetic marker-based screening programs. 6.3 Healthcare system adaptation Implementing genetic marker-based screening and prevention strategies necessitates significant adaptations within healthcare systems. This involves developing appropriate clinical guidelines, training healthcare providers, and ensuring the necessary infrastructure and technology are in place (Lu et al., 2020). Healthcare providers must be trained not only in administering and interpreting genetic tests but also in counseling patients about the results and their implications for clinical management. Furthermore, integrating genetic testing into existing screening programs requires standardized protocols for follow-up care, including risk stratification and management for individuals identified as high risk. Additionally, healthcare systems need to establish reliable data management systems to handle complex genetic information securely and accurately. In many regions, especially low- and middle-income countries (LMICs), the lack of infrastructure and trained personnel presents a significant barrier to adopting genetic marker-based screening. Therefore, healthcare systems must invest in technology, workforce training, and sustainable strategies to make genetic screening accessible and effective on a larger scale. 7 Future Directions in Cervical Cancer Screening and Prevention 7.1 Integration of genetic and traditional methods Future advancements in cervical cancer screening are likely to involve integrating genetic marker-based screening with traditional methods like Pap smears and HPV DNA testing. This combined approach aims to enhance both the sensitivity and specificity of screening programs, improving early detection rates while minimizing false positives. For example, co-testing with HPV DNA and Pap smears has already proven more effective in identifying high-grade lesions than either method alone. Incorporating genetic markers, such as DNA methylation patterns and gene mutations, into this screening framework could further refine risk stratification. Women who test positive for high-risk HPV but show no cytological abnormalities might undergo additional genetic marker testing to evaluate their risk of progression to cervical cancer, thus reducing unnecessary colposcopy referrals and overtreatment (Zhang et al., 2022). This integration marks a shift toward a more personalized screening approach, allowing for more targeted interventions and enhancing the overall efficiency of cervical cancer prevention programs. 7.2 Innovative biomarker research Ongoing research into novel biomarkers offers exciting potential for the future of cervical cancer screening. In addition to DNA methylation and HPV-related genetic mutations, emerging biomarkers such as microRNAs
