In clinical practice, HPV testing is mainly required after marriage or sexual intercourse for more than 3 years, or if you are over 30 years old. At present, the cause of cervical cancer has been found to be cervical cancer caused by high-risk HPV infection in the cervix. Therefore, in clinical practice, regular HPV checkups can detect any abnormalities in the cervix. If there is a high-risk HPV infection, you need to know whether the cervical epithelium has developed lesions, and if lesions have occurred, timely treatment should be given to prevent the occurrence of cervical cancer, so it is very important for women to do HPV examination and cervical cancer screening.
