If cervical lesions refer to the treatment of cervical squamous intraepithelial lesions, they are divided into low-level squamous intraepithelial lesions and high-level squamous intraepithelial lesions according to the degree of cervical squamous intraepithelial lesions. About 60% of low-grade squamous intraepithelial lesions will naturally subside, so this part of patients can be followed up for observation. During the follow-up, patients with lesions that have developed or persist for two years also need treatment. Cryotherapy, laser or cervical circular electrosurgical excision procedure, also known as "coal seam EEP" surgery, is currently mostly used in the cervical coal seam EEP surgery. If it is a high-grade squamous intraepithelial lesion that can develop into an invasive cancer and needs timely treatment, cervical conization can be performed. If the elderly cervical atrophy or no fertility requirements, or there are other benign gynecological disease surgery pointer, can also be performed hysterectomy.
