Low-grade squamous intraepithelial lesion (LSIL) occurs in a relatively large number of people and is a common type of abnormal cervical cytology result, with an incidence of about 5%, which means that for 100 people who have a cervical cytology test, about 5 people can have low-grade squamous intraepithelial lesion. Those who develop low-grade squamous intraepithelial lesion lesions should routinely undergo colposcopy and follow-up, with the aid of colposcopy to comprehensively assess the female lower genital tract to monitor the progression of cervical lesions and avoid missed diagnoses.
