Many women are often told that they have varying degrees of “cervical erosion” when they visit a gynecological clinic for a gynecological examination, and some women have a lot of psychological pressure to do this, and even try to seek treatment by all means. In fact, “cervical erosion” is not really erosion, nor is it a manifestation of chronic cervicitis, but rather the ovarian secretion of estrogen that causes the squamous-columnar junction of the cervix to migrate out to the vaginal part of the cervix, causing a “celiac-like” change in the cervix, which is now known by expert consensus as “cervical columnar”. This is now known as “cervical columnar epithelial ectasia”. When cervical ectopic changes are detected, a cytologic examination of the cervix (TCT) should be performed to determine if there is intraepithelial neoplasia or cervical cancer in the cervix for further investigation and treatment. Secondly, it is important to clarify the presence of mucopurulent cervicitis. Such women often have increased vaginal discharge that is mucopurulent and may present with symptoms such as intermenstrual bleeding or post-coital bleeding. Gynecologic examination reveals cervical congestion and edema, mucous membrane ectasia, mucopurulent discharge attached or even flowing from the cervical canal, and contact bleeding from the cervix. Testing of cervical or vaginal secretions can help clarify the diagnosis, and some pathogenic tests can also be performed to clarify the pathogen so that systematic targeted anti-inflammatory treatment can be taken. For some physiological (adolescence, pregnancy, childbearing age) cervical erosion-like changes, which exclude infections and pathological “erosions”, treatment is not necessary if there are no symptoms.
