In the gynecological clinic and network consultation often encounter women friends due to “celiac disease” consultation, requesting treatment, and some have even spent a lot of laser, microwave, leep knife surgery, intravenous rehydration and other unindicated, unnecessary treatment. The actual fact is that you can’t help but feel sad whenever you encounter such patients, and you can’t bear to tell the patients who are being deceived. So, is “celiac disease” a disease? Should we treat it or not? First of all, “cervical erosion” is not a disease diagnosis, but a customary description of the appearance of the cervix by doctors, now renamed “cervical columnar epithelial ectasia”, a physiological state of the cervix. Secondly, “cervical erosion” is related to the level of female hormones. The cervical epithelium mainly has two kinds of epithelial cells, one is squamous epithelial cells and the other is columnar epithelial cells. The female cervical squamous-columnar junction is affected by estrogen secreted by the ovaries, and the columnar epithelium of the cervical canal proliferates and moves outward from the mouth of the cervical canal, making the tissue in the area look granular and red to the naked eye, resembling erosion. According to the size of the outward migration of the columnar epithelial hyperplasia, the so-called “cervical erosion” is clinically classified into: degree I (mild), degree II (moderate) and degree III (severe). The majority of what is commonly referred to as “cervical erosion” is not “true erosion” but “pseudo-erosion”, which is ectopic cervical columnar epithelium, not a disease and does not require treatment. The cervical columnar epithelium is thin and susceptible to infection by pathogens, which can lead to acute and chronic cervicitis, covered by purulent surface discharge, manifesting as increased yellow purulent leucorrhea, thus requiring treatment, usually short-term local medication. If the effect of medication is not good and bad cervical lesions are excluded, physical therapy such as cervical laser can be considered. The appearance of the cervix of patients with precancerous cervical lesions and early stage cervical cancer is indistinguishable from “cervical erosion” and cannot be identified by the naked eye, so standardized tests are needed to identify them. Women who are married or have been sexually active for more than three years need to be screened every 1-2 years to rule out or detect cervical dysplasia through HPV testing, cervical cytology smears (TCT or Pap smears), colposcopy, etc., and receive timely and effective treatment. Note that even women with a smooth cervical appearance may have early cervical cancer or precancerous lesions.
