The cervix is an important part of the female reproductive organs and is closely related to women’s lives and fertility. Cervical erosion is a problem for many women. “Cervical erosion is the result of the replacement of the squamous epithelium on the outside of the cervix by a single layer of columnar epithelium in the mucous membrane of the cervical canal. It is a physiological change caused by hormonal changes in the female body and is not a disease. The term “cervical erosion” is derived from the English translation of Cervicalerosion, but at the time the translation was somewhat inappropriate, calling erosion the meaning of erosion, when in fact erosion has multiple meanings of loss of epithelium, epithelial shedding or ulceration. For a long time, it has been used incorrectly, resulting in a lot of over-medication of the cervix and adding a lot of unnecessary worry to patients. Now the obstetrics and gynecology community is aware of the seriousness of the problem and has abandoned the term “cervical erosion” and replaced it with “cervical columnarectopy”. It is not considered to be a pathological change, but a physiological change of the cervix. However, due to long-term habits into nature, there are many physicians who have not changed their minds and still call it “cervical erosion”, and even more, some medical institutions and commercial advertisements make a big deal about it for economic interests, making people more afraid of “cervical erosion”. The high incidence of cervical erosion in women during their reproductive years is due to the high ovarian function and high estrogen levels in the body, causing the columnar epithelium in the cervical canal to migrate out to the surface of the cervix to replace the squamous epithelium, a physiological change. In fact, the birth of a baby girl’s cervix is also “erosion”, which is due to the role of maternal estrogen in the body, to be born a few days later, the body estrogen decline, the columnar epithelium back to the cervical canal, the cervix is smooth. Most postmenopausal women have a smooth cervix due to low estrogen in the body. The actual cervical cancer is not cervical cancer, not precancerous; 4, should not make a big deal on the word “cervical” and advertising, misleading people; 5, cervical erosion is not cervical cancer, not precancerous; 4, should not be on the word “erosion” and advertising, misleading people; 5, cervical erosion is not cervical cancer, not precancerous; 5, cervical erosion is not cervical cancer, not precancerous; 5, cervical erosion is not cervical cancer, not precancerous; 6, cervical erosion is not cervical cancer. 5, gynecological examination found “cervical erosion”, do not panic, according to the formal cervical disease screening; 6, “cervical erosion” whether treatment, depending on whether the co-infection, whether there are symptoms. If you have no symptoms and no co-infection, you do not need treatment; if you have symptoms and co-infection, such as increased discharge and contact bleeding, you should be given medication or physical therapy after a negative cytology test; 7. There are no specific diagnostic criteria for cervical hypertrophy, but the key is that there is no therapeutic significance, i.e. no treatment is needed.
