Cancer is scary, but cervical cancer is not. Currently, cervical cancer is really a preventable and treatable disease at an early stage, and the means to prevent and treat it is to have regular cervical cancer screening, that is, TCT and HPV testing, which can be achieved by taking materials during a simple gynecological examination. There are many pathological types of cervical cancer, among which cervical squamous carcinoma accounts for 90%. The evolution of this type of cervical cancer is cervical precancerous lesion (CIN) I, II, III until cervical cancer, which takes about 2-10 years. Therefore, cervical cancer screening is mainly to detect cervical precancerous lesion, i.e. cervical epithelioid neoplasm, and to further intervene for the purpose of preventing and treating cervical cancer. When abnormalities are found in cervical cancer screening, colposcopy is usually performed further. If the biopsy indicates the presence of pre-cancerous lesions, do not be nervous because it is not cancerous and we either observe it closely without surgery depending on the specific situation and level, or perform cervical sleep surgery to prevent future cancer. It should also be noted that symptoms of abnormal vaginal discharge, excessive leucorrhea or vaginal bleeding after sexual intercourse should be promptly checked.
