High-risk HPV type 18 infection increases the risk of cervical cancer, but the incidence is very low. It takes more than 10 years for HPV infection to develop into cervical cancer, but most patients can turn negative with treatment. HPV18 and HPV16 are the high-risk HPV types that cause cervical cancer, but HPV18 and HPV16 positivity does not necessarily mean that you have cervical cancer and further colposcopy is required to confirm the diagnosis. Generally, only 12 months of persistent infection is associated with the possibility of developing cervical cancer. Persistent high-risk HPV infection is a major risk factor for cervical cancer, and more than 99% of cervical cancers are associated with high-risk HPV infection. Patients with early stage cervical cancer often have no obvious symptoms and signs, but with the development of lesions, patients may experience symptoms such as irregular vaginal bleeding and abnormal vaginal fluid discharge. Therefore, patients with HPV18 and HPV16 need to undergo colposcopy to find out whether precancerous lesions occur in the cervical epithelium. Those who do not have precancerous lesions also need to be reviewed regularly. Those who have precancerous lesions should be given appropriate treatment according to the degree of lesions, and if they turn negative, cervical cancer will not occur. In addition, during the treatment period, patients should pay attention to drink more water, increase the intake of fresh fruits and vegetables, avoid spicy and stimulating food, and can increase exercise to improve the body immunity.
