A positive cervical biopsy for P16 indicates a cervical infection with HPV type 16, which means that it is currently infected or has been infected in the past and belongs to the high-risk group of viruses that can easily develop into cervical tumors. Therefore, it is also necessary to have regular review and watch for any other uncomfortable symptoms. Cervical infection with HPV is mainly through sexual transmission, so it is important to avoid multiple sexual partners and sharing sanitary ware with patients infected with the virus. Women who need cervical biopsy are mainly patients with long-term chronic cervicitis, cervical erosion and cervical tumors. It is recommended that middle-aged and older women should undergo annual cervical exfoliation cell examination and cervical biopsy in case of abnormalities in order to achieve early detection and early treatment to avoid the development of cervical tumor.
