If you are tested positive for HPV during cervical pre-cancer screening, you need to be retested after 6 months to 1 year at this time, using a special brush to take off cervical tissue cells around the cervical opening and then check the virus, which is HPV retest. This is because high-risk HPV infection, if persistently infected for more than 2 years, may cause cervical precancerous lesions, which may then progress to cervical cancer in 5-10 years if not treated in time. If the HPV test is positive, it is important to review regularly and have both TCT and HPV checked at the same time during the review.
