HPV infection, in fact, can exist as a human papillomavirus infection, and there is a chance of precancerous lesions. Women may have an 80% chance of HPV infection in their lifetime, and when they are positive for HPV infection, they should decide whether to undergo a biopsy according to their situation. However, when HPV16 or HPV18 is present, it is considered a more serious HPV infection and a cervical biopsy must be performed to rule out the possibility of cervical cancer. If there is frequent contact bleeding and frequent leukorrhea, a cervical biopsy should be performed to determine whether the infection is low-grade or high-grade intraepithelial neoplasia. As long as the result is low-grade benign, then vaginal plugs can be administered to help turn HPV negative.
