What are the high-risk factors for cervical cancer? The first one is viral infection. As we all know, hpv virus, also known as human papilloma virus, especially the positive high-risk type 16 and 18 of the virus, is closely related to cervical cancer, and the long-term infection of these two high-risk types of virus is the main factor causing cervical cancer. There is a clinical summary that about 90% of cervical cancer patients have long-term high-risk hpv virus infection, so hpv virus is a high-risk viral infection and is a high-risk factor for cervical cancer. The second high-risk factor is multiple sexual partners, which also increases the risk of hpv infection, because the most important way of transmission of hpv virus is sexual transmission. The third high-risk factor is the young age of sexual debut. Generally, women who have sexual debut at the age of less than 16 have an increased chance of cervical cancer infection. Also, young age at first birth and multiple pregnancies and births are also high-risk factors for cervical cancer. Therefore, the first risk factor for cervical cancer is hpv infection, the second is multiple sexual partners, the third is having sex for the first time at too young an age, the fourth is having sex for the first time at too young an age, and the fifth is having multiple pregnancies and births.
