HPV infection is clinically benign and is divided into high-risk and low-risk types. High-risk HPV infection, if persistent in the cervix or vagina, may cause local precancerous lesions and may even develop into cervical cancer. Therefore, if a high-risk HPV infection is detected, colposcopy must be done first to find out whether there are local mucosal or epithelial lesions, and if lesions are found, active treatment should be given to prevent the occurrence of cervical cancer. It is also recommended that women should insist on annual cervical screening even if they are not uncomfortable, to find out whether there are local lesions and whether they have high-risk HPV infections through screening.
