HPV, known as papillomavirus in Chinese, is as widely distributed in humans and animals as the influenza virus, except that infection of the cervix has the potential for cervical lesions and even cervical cancer. At present, about 80 types of HPV have been identified, and their infected epithelial sites are divided into skin-type HPV and genital tract epithelial HPV, about 35 types are involved in genital tract infections, and about 20 types are related to tumors, of which the closest relationship with cervical cancer is HPV types 16 and 18. According to statistics, HPV can be detected in 98% of patients with cervical cancer, while HPV-negative people almost never develop cervical cancer. In addition, HPV is present in more than 98% of patients with cervical lesions, meaning that high-risk HPV infection is the main cause of cervical pre-cancer and cervical cancer. HPV screening allows you to know exactly whether you are in the high-risk group. If you under the guidance of your doctor for regular review and actively take effective measures to block HPV infection, you can minimize the occurrence of cervical lesions.
