Before talking about cervical erosion, we should first make sure that there is no cervical erosion in the latest clinical application guidelines. This disease has been canceled and replaced by displacement of cervical columnar epithelium. The columnar epithelial displacement of the cervix is a normal physiological phenomenon, not a disease, so there is generally no need to worry about it or treat it. Grade I cervical erosion refers to the slight outward migration of cervical columnar epithelium, which may be asymptomatic or may have a slight increase in leucorrhea. Most doctors will say this during gynecological examination, because most of them will not pay attention to it clinically when there is no symptom, and this kind of disease does not need treatment. At ordinary times, pay attention to personal cleanliness and hygiene, keep the vulva dry, keep the vagina clean, and change your underwear frequently to observe. However, once there is abnormal vaginal bleeding or cervical contact bleeding, it is necessary to go to the hospital for further cervical screening and clear diagnosis.
