Cervical erosion is not true erosion, but an outgrowth of a single layer of columnar epithelium that originates in the mucosa of the cervical canal and can be seen in the cervical vessels below the period. It looks like celiac disease and has been used for a long time, so many scholars advocate discarding the term ”celiac disease” and replacing it with: displaced cervical columnar epithelium. Because of the low resistance of the cervical canal columnar epithelium, pathogens can easily infiltrate and inflammation occurs. For the treatment of cervical erosion, foreign scholars believe that no clinical symptoms need not be treated, only cytological screening is done and if the cytology is abnormal, the corresponding treatment is done according to the cytological results, but some scholars believe that because of the low resistance of the columnar epithelium, inflammation easily occurs and there should be corresponding treatment measures, but there is so much over-treatment.
