The examination items of the cervix are mainly the three steps of cancer prevention and screening, the first step is TCT (liquid-based thin layer cytology) and HPV (human papillomavirus), the second step is colposcopy, and the third step is pathological tissue examination. During the examination, some basic checks are also done to check whether there are abnormal changes in the morphology of the cervix, such as polyps, obvious inflammatory manifestations, etc., as follows: 1. TCT, HPV Testing: TCT and HPV alone or in combination, if there is no problem, regular review can be done later; 2. Colposcopy: Colposcopy can magnify the image of vagina and cervix, and at the same time apply the reagent that can make the lesion colored, the lesion can also be magnified after the lesion is colored. Examination: It is a pathological examination that can clarify whether there is any lesion in the cervix. If there is no lesion, it can be reviewed regularly in the future, and if there is a lesion, it is common to find precancerous lesion in the cervix. Pre-cancerous lesions are differentiated into grade I, grade II and grade III. Some grade I lesions are self-reversible and do not necessarily require surgery, while grade II-III lesions usually require surgery. Surgery is often performed by laparoscopic conization of part of the cervix for laboratory testing, or cold knife conization to stop the further development of the lesion towards cervical cancer. If early stage cervical cancer has already occurred, corresponding treatment can also be done and the results are usually better.
