Cervical cancer precursor

Cervical precancerous lesions can be detected by HPV and TCT examination. Cervical precancerous lesions can be divided into low-grade intraepithelial neoplasia (LSIL) and high-grade intraepithelial neoplasia (HSIL). about 60% of LSIL will naturally regress. During follow-up, the development or persistence of lesions should be treated. HSIL can develop into invasive cancer and need treatment. Some HSIL can be manifested as bleeding after cohabitation.
