What Causes Grade I Cervical Erosion?
Hearing the term “cervical erosion” may cause anxiety. But what exactly is cervical erosion? In fact, this condition has long puzzled women in clinical practice. It was not until 2008 that medical textbooks officially replaced the term “cervical erosion” with “cervical ectropion” (or “ectopic columnar epithelium”).

Cervical ectropion results from estrogen-induced displacement of the cervical epithelium, clinically manifesting as an appearance resembling erosion. If a woman experiences no increase in vaginal discharge, no foul odor, and no yellowish vaginal discharge, no treatment is required.

Clinically, cervical ectropion is considered a physiological phenomenon—specifically, the outward migration of columnar epithelium—and typically requires no treatment, only routine follow-up examinations.
