It is a normal physiological phenomenon in the clinic, mainly due to the strong secretion of estrogen in women of childbearing age, which leads to the ectopic cervical columnar epithelium, which is clinically similar to erosion, so it is clinically called cervical erosion. The ectopic columnar epithelium moves back into the cervical canal and clinically clears up on its own, and the surface of the cervix becomes smooth again. Cervical erosion is a physiological phenomenon that does not cause any discomfort and does not need to be treated clinically. However, it is recommended to have an annual gynecological examination and cervical cancer screening to find out if there are lesions on the cervical epithelium.
