Cervical erosion has been translated as "cervical erosion", but the foreign authority of obstetrics and gynecology textbooks can not find the diagnosis of "cervical erosion" of.
In 2008, before the "Obstetrics and Gynecology" on cervical erosion has been used as a standard for the presence of disease, and even comes to its clinical manifestations, diagnosis and treatment. Before the doctor of obstetrics and gynecology, the physiology of cervical columnar epithelium appears as valgus is a pathological phenomenon. In 2008, the undergraduate seventh edition of "Obstetrics and Gynecology" Textbook Cancel "cervical erosion" disease name to "ectopic cervical columnar epithelium" physiological phenomenon substituted. Cervical erosion is a kind misconceptions past performance of normal cervix.
Cervical erosion correct to say that ectopic cervical columnar epithelium. This is a physiological phenomenon menstrual period occurs cervical columnar epithelium valgus. Although ectopic cervical columnar epithelium is not unusual, but it is difficult to distinguish early cervical cancer, and therefore must be further examination to differential diagnosis.
On the site of the cervix, there are two different types of cells, is close to the vaginal squamous cell, and that direction is close to the uterus columnar epithelial cells. Columnar epithelial cells and squamous epithelial cells are in a dynamic equilibrium, somewhat similar to war together stalemate area, this area in medicine was named "squamous columnar junction."
Squamous columnar junction susceptible to estrogen influence. Female before puberty, ovarian function is not perfect, low estrogen, columnar epithelium on the inside by some, to come after menstruation, columnar epithelium on the subject under the influence of estrogen, more outward development, and therefore we have more similar "erosion" as columnar epithelium in the cervix. After menopause, women estrogen levels decline, the columnar epithelium began to return within the party, "erosion" also invisible. Essentially speaking, the so-called cervical erosion, in fact, columnar epithelium valgus).
In medical textbooks in the past, as well as so-called indexing diagnosis of cervical erosion, known as mild, moderate and severe, the area is slightly less than 1/3, 1 / 3-2 / 3 is moderate, more than two / 3 is severe. This is actually a different extent by the effects of estrogen columnar epithelium valgus, whether mild, moderate, severe, is a normal physiological phenomenon.
There are many baby birth accompanied by ectopic cervical columnar epithelium, which is by the mother during pregnancy when hormone levels increased influence after birth, the symptoms will subside.
Since it is a normal physiological phenomenon, naturally without treatment. According to this physiological phenomenon to determine whether cervical damage is unfounded. However, cervical and regular checks are still necessary, mainly to prevent cervical cancer.
