Cervical cysts are not tumors, they are just normal secretions of the cervix that cannot be discharged, so there is no need to be alarmed. The reason is that during the healing process of cervical erosion, the new squamous epithelium covers the mouth of the cervical glandular duct or extends into the glandular duct, blocking the mouth of the glandular duct; or the connective tissue around the glandular duct grows or scar forms to compress the glandular duct, making the glandular duct narrow or even blocked, and the drainage of glandular secretion is obstructed and retained to form cysts. If the cyst is large, or if it is infected, microwave treatment or laser treatment can be used. Ding Xilai, Department of Gynecology, Beijing Meizhong Yihe Women’s and Children’s Hospital
