Cervical inflammation is not cervical erosion. Firstly, cervical erosion is merely a physiological phenomenon, where elevated estrogen levels in a woman's body cause the downward and outward movement of the columnar epithelium of the cervix. This condition is mainly seen in women of childbearing age. For instance, postmenopausal women generally have lower levels of estrogen, making cervical erosion less common. For example, during pregnancy, elevated estrogen levels can increase the area of cervical erosion. After childbirth, as estrogen levels gradually return to normal, the area of cervical erosion might reduce and might even become invisible. However, cervical inflammation is caused by pathogenic microorganisms. For example, a common scenario is vaginal inflammation spreading to the columnar epithelium of the cervix in some women. Additionally, some women experience sexually transmitted diseases, like the common infection of Neisseria gonorrhoeae, which causes inflammation of the columnar epithelium. Therefore, there is a fundamental difference between cervical inflammation and cervical erosion; cervical inflammation is a pathological change, while cervical erosion is a physiological change.
