Risk Factors and Causes
- Persistent infection with high-risk HPV types, particularly HPV-16 (70% of cases) and HPV-18 (20%), is the primary cause of cervical cancer
- Women with HIV have a 6-fold higher risk of developing cervical cancer due to impaired immune response to HPV

Risk Factors and Causes Interpretation
Cervical cancer statistics reveal a sobering conspiracy of biology and circumstance, where the common human papillomavirus exploits any vulnerability—be it a weakened immune system from HIV, the cellular damage from smoking, or even the hormonal shifts from long-term birth control—to transform from a ubiquitous infection into a preventable tragedy.
