INTRODUCTION

  • Cervical cancer, largely preventable and HPV-linked, remains a major public health burden in India. Vaccination (primary prevention) and screening (secondary prevention) are key interventions to reduce incidence and mortality.

VACCINATION: PRIMARY PREVENTION

  • HPV vaccines provide pre-exposure protection against high-risk strains (e.g., HPV-16, 18).
  • Evidence shows ~85–90% reduction in risk, especially when administered to adolescents.
  • Supports long-term decline in incidence and mortality.

SCREENING: SECONDARY PREVENTION

  • Pap smear and HPV DNA tests enable early detection of precancerous lesions (CIN).
  • Timely intervention prevents progression to invasive cancer.
  • Cost-effective tool for population-level control.

ACCESS AND AWARENESS

  • Low screening coverage (<5%) in India limits effectiveness.
  • Barriers include social stigma, lack of awareness, and rural-urban disparities.
  • Vaccine uptake constrained by cost and hesitancy.

HEALTH SYSTEM CAPACITY

  • Gaps in infrastructure, trained personnel, and follow-up care.
  • Weak test–treat continuum leads to drop-offs after diagnosis.

ANALYSIS

  • Vaccination offers high preventive potential, while screening ensures early detection and treatment.
  • However, fragmented implementation and limited outreach reduce overall impact.

WHAT HOLDS AND WHAT NEEDS QUALIFICATION

  • Holds true: Combined use of vaccination and screening can substantially reduce disease burden.
  • Needs qualification: Outcomes depend on high coverage, awareness, and continuity of care.

CONCLUSION

  • A significant reduction in cervical cancer burden requires universal HPV vaccination, expanded screening coverage, improved awareness, and strengthened health systems to ensure an effective prevention-to-treatment continuum.
