^*Pap results at the visit when precancer was detected.

CIN, cervical intraepithelial neoplasia; ASC-US, atypical squamous cells of undetermined significance; ASC-H: atypical squamous cells, cannot rule out high-grade lesion; LSIL, low-grade squamous intraepithelial lesion;

HSIL:CIN2: high-grade squamous intraepithelial lesion, favor moderate dysplasia; HSIL:CIN3: high-grade squamous intraepithelial lesion, favor severe dysplasia or carcinoma in situ.
