In general, HPV and TCT are examined once every 1-2 years. If no problems are found in cervical TCT and HPV examination, the interval can be extended appropriately, but if there are problems in the above two examinations, such as the presence of atypical squamous epithelial cells in TCT, or cervical HPV examination suggesting positive high-risk viruses, especially positive for types 16 and 18, in Follow-up colposcopic cervical biopsy should be performed at this time, and if the cervical biopsy is problematic, a subsequent conical hysterectomy should be performed. If the colposcopic cervical biopsy is fine at this time, but the interval between cervical TCT and HPV examination should be shortened, preferably after 3-6 months, so how often the above mentioned HPV and TCT examinations should be performed is different for each individual.
