Primary HPV screening provides 60–70 percent greater protection against invasive cervical cancer than cytology-based screening
A study of four European trials found that HPV-based screening provided greater protection against invasive cervical cancer than cytological screening. The analysis showed that HPV-based screening protected 60-70% more women from invasive cancers, with increased protection seen in women aged 30-35 years and those screened every 5 years.
