High-risk HPV31 infection usually takes 5-10 years to develop into cervical cancer, but it is not certain that you will get cervical cancer if you are infected with high-risk HPV, only that the probability of getting cervical cancer is higher than that without HPV infection. HPV infection is a long-term process, HPV31 is latent in the cells, once the body’s immunity decreases, the latent virus can resume its activity, which can cause low-grade squamous intraepithelial lesions in the uterus, and further develop into high-grade squamous intraepithelial lesions with cancerous potential in the long term, i.e. precancerous lesions. HPV31 high-risk infections need to be reviewed regularly every 6 months to 1 year, and for older women, colposcopy should be performed if necessary to rule out cervical lesions. If colposcopy does not reveal cervical lesions, you can use interferon vaginal pessary treatment and temporarily abstain from sexual intercourse to strengthen your resistance. Patients with HPV infection should not stay up late, take regular rest and rest, eat a balanced diet, exercise every day to improve immunity and increase the chance of HPV conversion, and pay attention to personal hygiene and avoid intercourse during treatment to prevent cross-infection.
