Cervical erosion: The cervical epithelium is composed of squamous epithelium of vaginal origin and columnar epithelium of cervical canal origin. When covered by the columnar epithelium, the cervix appears granular pink, which is somewhat like celiac disease, so it is called celiac disease; it is a normal physiological phenomenon. The higher the estrogen level, the heavier the “celiac disease”, in other words, the younger the celiac disease, the heavier it is, so it is also known as a symbol of youth. However, this kind of celiac disease has nothing to do with cervical cancer. The elderly can have a smooth cervix, but they can also have cervical cancer, while a young person with a smooth cervix does not have cervical cancer. It may be considered as cervical erosion and treated, but it is actually normal. Treatment is only needed when there is abdominal pain, increased leucorrhea, yellow smell or purulence, which means cervicitis. Cervical cancer is one of the most prevalent gynecologic malignancies in the world and the only one with a clear cause. High-risk human papillomavirus (HPV) infection is the cause of cervical cancer. Formal cervical cancer screening should start with cervical smear (TCT), HPV test and colposcopic biopsy if there is any problem. If there is a problem with the biopsy, treatment is determined by the patient’s specific situation, such as the presence or absence of children. For young women, the HPV infection rate is as high as 50% or more due to an active sex life, but due to the high immunity of the body, it mostly turns negative within 9-18 months. There are more than 100 types of HPV known, of which low-risk types are the cause of condyloma acuminata, and only a very small number of high-risk HPV (16, 18) persistent infections can cause cervical cancer precancerous lesions. There are two types of HPV tests, one for quantitative and one for high-risk typing, and typing must be done when quantitative increases. The American Colposcopy Society, after extensive clinical trials, has come to the following conclusion: cervical erosion is not associated with cervical cancer. There is a direct relationship between cervical cancer and HPV. HPV causes cervical cancer by going through the cervical neoplasia (CIN) stage, which is classified as I, II and III depending on the severity. This process can take years or even more than a decade and is associated with smoking, use of birth control pills, and sexually transmitted diseases. Only a very small number of high-risk HPV persistent infections can become cervical cancer. Therefore, cervical cancer is completely preventable and treatable. CIN I is related to HPV 6, 11, 31 and 35, and more than 70% of them can be turned into normal; CIN II and CIN III are difficult to distinguish clearly, so these two levels should be handled carefully; CIN III includes some in situ cancers related to HPV 16, 18 and 33, which should be handled actively. Nowadays, many young women are subjected to various excessive treatments due to the so-called cervical erosion. In addition to the economic cost, more serious is the damage to the cervix caused by inappropriate treatments that affect future fertility. The reasons for this are, on the one hand, the patient’s fear of cervical cancer and, on the other hand, the doctor’s lack of knowledge or the pursuit of profit. Random treatments such as cervical laparoscopy and microwave cause damage to cervical function, resulting in infertility or miscarriage and premature birth. In conclusion, it is recommended that patients with cervical erosion go to a regular hospital, undergo further examination and do not blindly over-treat. HPV currently has no evidence of adverse effects on the fetus, but lesions above CIN III can worsen during pregnancy, especially in patients who have been diagnosed with cervical cancer.
