Cervical grade III lesions can be treated with cervical conization, including cervical loop electrosurgery and cold knife conization, and if necessary, total hysterectomy is also required for cervical grade III lesions. Cervical grade III lesions refer to CIN grade 1, also known as cervical intraepithelial neoplasia grade III, which is a precancerous lesion of cervical cancer and includes the following two conditions: first, atypical squamous cells occupy the whole layer of the cervical epithelium; second, carcinoma in situ of the cervix has been detected but has not broken through the dermis of the cervix. Cervical grade III lesions are a previous pathological classification of cervical lesions, but the latest classification now calls them cervical squamous intraepithelial lesions, which are divided into two grades: low-grade cervical squamous intraepithelial lesions and high-grade cervical squamous intraepithelial lesions, as follows: First, low-grade cervical squamous intraepithelial lesions: they are equivalent to CIN grade 1, and approximately About 60% of women can regress naturally, so for low-grade squamous intraepithelial lesions, observation is usually used. Second: High-grade cervical squamous intraepithelial lesions: they are already cervical precancerous lesions, so for high-grade cervical squamous intraepithelial lesions, such precancerous lesions should be treated actively by cervical conization or total hysterectomy. However, the treatment method is different for different people, and different treatment options can be chosen according to the doctor’s recommendation.
