Cervical cancer is a malignant tumor that occurs from the cervical coating epithelium and glandular epithelium. It almost always occurs in women with a history of sexual intercourse or multiple births. Cervical cancer is the most common gynecological malignancy, accounting for more than half of the malignant tumors of the female reproductive system. The onset is related to early marriage, early childbearing, multiple births, close births, multiple marriages, early or frequent sexual intercourse, and low immune function. Patients with cervical cancer usually have HPV infection, which often manifests as contact vaginal bleeding, irregular vaginal bleeding after menopause, increased vaginal discharge, etc. Early examination of the cervix is mostly erosion-like changes. However, not all early stage cervical cancer has detectable signs and positive signs. Some are detected during screening. The progression of cervical cancer is quite slow, from viral infection to cervical cancer in 8-10 years. Moreover, early cervical cancer or precancerous lesions and cervical erosion are difficult to determine clinically. If we can detect precancerous lesions at the stage of pre-cancerous lesions, it is much easier to treat and less damaging, and at the same time, we can stop the development towards cervical cancer. Therefore, cervical cancer can be prevented, and the prognosis of early cervical cancer is quite good after treatment. Therefore, if early detection, early diagnosis and early treatment can improve the quality of life of patients and reduce the mortality rate of the disease. At present, the main examination methods are cervical HPV and TCT, followed by cervical colposcopy if there is any abnormality and cervical biopsy if necessary. There are many treatment methods for cervical precancerous lesions. Early cervical squamous intraepithelial neoplasia can be treated by physical therapy or cervical loop electrosurgery (LEEP), and for cervical squamous intraepithelial neoplasia grade III, because of the depth of the lesion, some patients may still have recurrence or even malignant change in the future, so total hysterectomy is feasible for patients who do not have fertility requirements and are over 40 years old, while cold knife conization of the cervix is feasible for those who are young or have the requirement of preserving fertility. In addition, LEEP is also available. Those with preserved uterus must be closely followed up after surgery with regular cervical cytology and colposcopic cervical biopsy for early detection of progressive trends. Even for early-stage low-risk cervical cancer, after radical cervical excision, there is no need for follow-up treatment such as radiotherapy or chemotherapy after surgery, and the recurrence rate is extremely low. For mid-stage cervical cancer or cervical cancer with large masses, adjuvant radiotherapy is needed after surgery, and sometimes adjuvant chemotherapy is needed before surgery to facilitate surgery. For advanced cervical cancer, it is no longer suitable for surgery and must be treated by radiotherapy. Therefore, the earlier the detection, the better the prognosis, and regular gynecological examination is necessary.
