Moderate cervical erosion alone is not serious. Cervical erosion used to be classified as mild, moderate or severe. At present, cervical erosion is no longer classified in this way. Simple cervical erosion may clinically be due to physiological changes caused by the outward migration of the columnar epithelium, called cervical erosion-like changes. Simple cervical erosion without abnormal bleeding or polyps does not clinically require specific treatment. Celiac disease that is combined with HPV infection, or TCT changes, should be treated clinically. Many clinical cases of cervical erosion are caused by changes in normal hormone levels. After menopause or menopause, the cervical erosion will become normal and the squamous epithelial erosion will disappear.
