The so-called “cervical erosion” is a fine-grained red area in the appearance of the vaginal part of the cervix at the external cervical opening, which used to be called “cervical erosion”. The “celiac” surface is covered by a single layer of columnar epithelium of the intact cervical canal, with red interstitial penetration underneath, but it is not true celiac disease. The real pathology of celiac disease is the epithelial fall, ulceration. In fact, the term “cervical erosion” has long been abandoned abroad, but the term “cervical columnar epithelial ectopic”. As the cervical canal columnar epithelium resistance is low, pathogens can easily invade the inflammation. It is worthwhile for clinicians and patients to note that in some normal physiological conditions such as puberty, pregnancy or women taking oral contraceptives, due to increased estrogen levels, the cervical canal columnar epithelium hyperplasia, the original squamous epithelial junction outward, replaced by the cervical canal columnar epithelium overw, so the ectocervix is visible in the form of red fine granular, resembling “erosion”. This is actually physiological cervical “erosion”. When the estrogen level drops the columnar epithelium can return to the cervical canal, the cervix will resume the squamous epithelium overw, the so-called “cervical erosion” will naturally “heal”. Therefore, this kind of “cervical erosion” does not require treatment, and I hope that clinicians will no longer use the diagnosis of “cervical erosion” in order to avoid misleading patients. Only when the cervix has inflammation or precancerous lesions does it need treatment, such as: 1. increased leucorrhea in the form of mucopurulent, itching and burning pain in the vulva; 2. irregular vaginal bleeding, bleeding after sexual intercourse; 3. frequent urinary urgency and painful urination; 4. cervical congestion and edema in the gynecological examination, with mucous purulent discharge in the mucous membrane ectasia; 5. precancerous lesions found in the cervical cancer prevention examination.
