Celiac disease used to be a disease that plagued many women. In 2008, the 7th edition of the textbook “Obstetrics and Gynecology” for undergraduates dropped the name “cervical erosion” and replaced it with the physiological phenomenon “cervical columnar epithelial ectasia”. Cervical erosion, in the end, is actually a misconception of a normal manifestation of the cervix in the past. Cervical columnar epithelial ectasia is a normal physiological phenomenon with no specific clinical manifestations. Some people may have contact bleeding, but it is just an individual difference of the cervix, just like some people chew something hard and their teeth or mouth will bleed a little. If there is an increase in leucorrhea, yellowing and odor, it is a sign of cervical inflammation. Cervical that cyst and hypertrophy are also the result of chronic inflammation of the cervix. Cervical columnar epithelial ectopic does not require any treatment, and the many treatments for cervical erosion nowadays are wrong. However, for symptomatic cervicitis, treatment is needed. Acute inflammation is treated with suppository medication and chronic inflammation can be treated with physical therapy methods such as laser or freezing. Regular examination of the cervix is necessary, not to prevent cervical erosion, but to prevent cervical cancer. The occurrence of cervical cancer is related to human papillomavirus (HPV) infection. Some patients with high-risk HPV infection are prone to precancerous lesions and cervical cancer when the infection persists in the squamocolumnar junction area of the cervix. Cervical cancer has seen a substantial decrease in mortality since the availability of cervical smears, and the key is early prevention and treatment. Currently, it is recommended that women after the age of 21 should have a cervical smear once a year, and after the age of 30, they can have a joint HPV test. If three consecutive HPV and cervical smear tests are negative, the interval can be extended to once every three years, and screening can be stopped after the age of 65.
