Cervical erosion is not considered a disease, so it is not serious. It is merely a physiological state, not an illness, so there is no need to worry or be concerned about the presence of cervical erosion. Simple cervical erosion is caused by higher levels of estrogen in young people, which can lead to the physiological ectropion of the columnar epithelium of the cervix. This is not a disease, but a physiological state, characterized by a bright red erosion-like appearance, which gradually diminishes with age.
