Additionally, AI-based image analysis of cervical cytology and histology samples has shown promise in reducing observer variability and increasing sensitivity in detecting precancerous lesions. The combination of machine learning with genetic marker-based screening could revolutionize cervical cancer screening programs, enabling more precise and early identification of high-risk individuals while optimizing resource allocation. 5 Genetic Markers for Cervical Cancer Prevention 5.1 Prophylactic vaccination and genetic markers Prophylactic vaccination against high-risk HPV types, particularly HPV16 and HPV18, has proven to be a highly effective primary prevention strategy for cervical cancer. Vaccines like Gardasil and Cervarix have shown significant reductions in the incidence of HPV infections and related cervical lesions. Recent research suggests that genetic markers could enhance the effectiveness of HPV vaccination programs by identifying individuals who are more likely to benefit from vaccination and those who may require additional interventions. For example, studies indicate that variations in the human leukocyte antigen (HLA) system may influence individual susceptibility to HPV infection and the response to vaccination (Espinosa et al., 2013). Understanding these genetic markers can help optimize vaccination strategies by targeting high-risk populations and monitoring vaccine efficacy more effectively. Additionally, genetic markers associated with immune response may inform the development of next-generation vaccines with broader coverage, enhancing their protective effects against various oncogenic HPV strains (Zhang et al., 2022). 5.2 Personalized prevention based on genetic risk The identification of genetic markers linked to an increased risk of cervical cancer paves the way for personalized prevention strategies (Chen, 2024). Individuals with specific genetic predispositions, such as alterations in genes involved in DNA repair, cell cycle regulation, and immune response, may be more likely to develop cervical cancer following HPV infection. Personalized prevention programs can incorporate genetic risk assessments to identify these high-risk individuals, allowing for tailored interventions like more frequent screenings, earlier initiation of screening, or the use of additional diagnostic tools such as DNA methylation panels. Furthermore, personalized strategies can inform decisions regarding HPV vaccination for older individuals or those who may have already been exposed to HPV, maximizing the vaccine's preventive potential by considering genetic susceptibility (Cohen et al., 2020). By integrating genetic risk factors with traditional screening and vaccination programs, personalized prevention has the potential to more effectively and efficiently reduce the incidence of cervical cancer. 5.3 Genetic testing in primary prevention Genetic testing has become an increasingly vital tool in primary prevention efforts for cervical cancer. Advances in genetic testing technologies, such as next-generation sequencing (NGS) and polymerase chain reaction (PCR)-based assays, enable the identification of high-risk genetic markers, including mutations in host genes and epigenetic modifications linked to an elevated risk of cervical cancer. This testing can pinpoint women at higher risk who may benefit from intensified screening protocols, even before any clinical symptoms or cytological abnormalities arise. For instance, women with specific genetic alterations, such as those in the TP53 or CDKN2A genes, may require more rigorous surveillance due to their increased likelihood of developing high-grade cervical lesions. Additionally, testing for DNA methylation markers has shown promise as a triage tool for HPV-positive women, offering a more precise risk assessment that can guide decisions on further diagnostic procedures and interventions. By integrating genetic testing into primary prevention strategies, healthcare providers can take a more proactive approach to cervical cancer prevention, ultimately reducing the burden of this disease through early intervention and targeted management. 6 Challenges in Implementing Genetic Marker-Based Screening and Prevention 6.1 Cost and accessibility issues One of the main challenges in implementing genetic marker-based screening for cervical cancer is the associated cost. Advanced technologies like next-generation sequencing (NGS) and DNA methylation testing can be
