As a precancerous lesion of cervical cancer, cervical squamous intraepithelial lesions have also been paid close attention by clinicians. In recent years, with the enhancement of women’s awareness of physical check-up and the improvement of screening methods for precancerous lesions, the detection rate of cervical squamous intraepithelial lesions is increasing year by year, and the age of the disease is gradually tending to be younger. Therefore, adopting of normative screening methods and treatment strategies which are timely and effective for patients suffering from cervical squamous intraepithelial lesions, is of great significance to reduce the occurrence of cervical cancer. The essay summarized the “three-step” screening content of cervical squamous intraepithelial lesions and related treatment strategies, in the meantime, it’s great importance of stratified management and individual management, hoping to provide new train of thoughts for delaying or preventing the progression of cervical squamous intraepithelial lesions and improving the clinical outcome of patients.展开更多
