When going to the clinic, there are always some patients asking the question: does cervical erosion need to be treated? Some patients have even had microwave treatment, leep treatment and antibiotic treatment for celiac disease in some small clinics, which not only suffer financially, but even bring physical and mental harm. In recent years there has been a new reference to cervical erosion, which is not really known as erosion, but is now called: Columnar Epithelial Displacement. It’s too specialized to explain: there are two types of epithelium on the cervix: columnar epithelium and compound squamous epithelium. In the neonatal period, the columnar epithelium is located in the cervical canal, and the part exposed to the vagina is the compound squamous epithelium, so the cervix looks smooth at this time. After puberty, with the increase of estrogen level in the body, the columnar epithelium located inside the cervical canal gradually moves to the outside of the cervical opening, forming the so-called erosion. After menopause, as the estrogen level decreases, the columnar epithelium gradually moves to the cervical os, and the cervix becomes smooth again. After this explanation, I would like to ask my patients to answer themselves: Is it still necessary to treat cervical erosion? Of course not! It is just a physiological phenomenon. Of course, this is only on the premise that the patient has no conscious symptoms and that the annual cervical cancer scraping is normal and free of precancerous lesions.
