1.INTRODUCTION

Cervicalcancerisoneofthemostpreventableyetprevalent cancers affecting women worldwide. Despite significant advancementsinmedicalscience,itcontinuestoaccountfor a substantial proportion of cancer-related morbidity and mortality,especiallyinlow- andmiddle-incomecountries. Thediseaseprimarilyarisesfrompersistentinfectionwith high-risktypesofhumanpapillomavirus(HPV),whichare strongly associated with cellular transformation and tumorigenesisinthecervicalepithelium.

Over the past few decades, innovative strategies for prevention and early detection have transformed the landscape of cervical cancer management. Widespread adoption of HPV vaccination programs has significantly reduced the prevalence of high-risk HPV infections,

particularly in younger populations. Simultaneously, advances in screening technologies, such as liquid-based cytology and HPV DNA testing, have enhanced early detectioncapabilities,enablingbettertreatmentoutcomes.

However, disparities in access to these technologies and preventive measures remain a significant challenge, particularlyinresource-limitedsettings.Theemergenceof noveltherapeuticapproaches,includingimmunecheckpoint inhibitors,molecular-targetedtherapies,andpersonalized medicine,hasopenednewavenuesfortreatingadvancedstageandrecurrentcervicalcancer.

women. The World Health Organization (WHO) estimates that over 600,000 new cases and 340,000 deaths occur annually, with the majority concentrated in developing countries. This disparity underscores the urgent need for equitable access to preventive and diagnostic resources. Persistent infection with high-risk human papillomavirus (HPV), particularly types 16 and 18, is the primary etiologicalfactor,accountingfornearly99%ofallcervical cancercases.

The natural progression of cervical cancer from a precancerous lesion to invasive disease provides a critical windowforpreventionand earlyintervention.Preventive measures, such as HPV vaccination, have been proven to drasticallyreducetheincidenceofhigh-riskHPVinfections and associated cervical lesions. Despite this, vaccination coverageremainsinconsistentglobally,largelyduetosocioeconomic,cultural,andlogisticalbarriers.

Advancementsinscreeningtechniques,includingtheuseof HPV DNA testing and liquid-based cytology, have significantlyimprovedearlydetectionrates.Thesemethods have demonstrated higher sensitivity and specificity comparedtotraditionalPapsmeartests,particularlywhen combined with risk-based algorithms. New screening strategies are also emerging, including self-sampling kits, whichholdpromiseforreachingunderservedpopulations.

For cases diagnosed at later stages, treatment remains a challenge.Whilestandardapproacheslikesurgery,radiation, andchemotherapyhaveimprovedsurvival rates, they are often associated with significant side effects and limited efficacy in advanced or recurrent disease.

3. SUMMARY OF LITERATURE SURVEY

Cervical cancer research has seen remarkable advancements in understanding its etiology, prevention, diagnosis, and treatment, alongside the development of impactfulpublichealthstrategies.Persistentinfectionwith high-riskhumanpapillomavirus(HPV),particularlyHPV-16 andHPV-18,istheprimarycauseofcervicalcancer.Studies have identified other risk factors, includingsmoking,early sexual activity, multiple sexual partners, and immunosuppression, whichincrease thelikelihood ofHPV infection progressing to cancer. These findings have been pivotal in designing prevention and screening programs worldwide.

One of the most significant advancements in cervical cancer prevention has been the development of HPV vaccines,suchasGardasilandCervarix.Thesevaccineshave demonstratedhighefficacyinreducingHPVinfectionsand precancerous cervical lesions, with substantial success in regionswithrobustvaccinationprograms.However,global implementationremainsuneven,especiallyinlow-resource settings,duetochallengessuchasvaccinehesitancy,lackof awareness, and logistical barriers. Addressing these disparities iscritical toachieving universal cervical cancer prevention.

Intherealmofscreeninganddiagnosis,HPVDNAtesting has emerged as a superior alternative to traditional Pap smears,offeringhighersensitivityandspecificityindetecting precancerous lesions. Advances in screening technologies, such as liquid-based cytology and AI-assisted diagnostics, have further improved accuracy and accessibility. Selfsampling techniqueshavealsoshown promise in reaching underserved populations, empowering women in remote areastoparticipateinscreeningprograms.Theseinnovations are vital in overcoming barriers to early detection, which remainsacornerstoneofcervicalcancercontrol.

Treatmentapproachesforcervicalcancerhaveevolved significantly,particularlyforadvancedandrecurrentcases. While traditional methodssuchassurgery,chemotherapy, and radiation remain central to treatment, emerging therapies are transforming outcomes for patients with aggressive or late-stage disease. Immune checkpoint inhibitors,likepembrolizumab,andtargetedtherapies,such asbevacizumab,haveshownpromiseinimprovingsurvival rates.Additionally,ongoingresearchintomolecularprofiling and personalized medicine aims to tailor treatments to individualpatients,maximizingefficacyandminimizingside effects.

Public health strategies have played a crucial role in reducingcervicalcancerincidenceandmortality.Organized vaccinationandscreeningprogramsinhigh-resourcesettings haveledtoasignificantdeclineincases,withsomecountries, likeAustralia,ontracktoeliminatecervicalcancerasapublic health problem. However, disparities in access to these programsremainasignificantchallenge,particularlyinlowand middle-income countries. The World Health Organization’s (WHO) Global Strategy for Cervical Cancer Elimination aims to address these challenges by setting ambitioustargetsforvaccination,screening,andtreatment by2030.

Despite these advancements, several challenges persist, including socio-economic disparities, limited healthcare infrastructure, and vaccine hesitancy. Future research is focused on enhancing early detection technologies, expanding access to preventive measures, and developing novel therapeutic approaches. The integration of scientific innovationwithrobustpublichealthinitiativesisessentialto achieving equitable cervical cancer control. As efforts continue, interdisciplinary collaboration will be key to overcomingbarriersandadvancingtowardthegoalofglobal cervicalcancerelimination.
