Cervical HPV virus screening is required in cervical cancer prevention because a lot of studies have found that there is an 80-90% correlation between HPV and the occurrence of cervical cancer, that is, HPV infection is an important factor in the occurrence of cervical cancer. 1. What is HPVHPV (humanpapillomavirus), or human papillomavirus, is a group of viruses that mainly infect human squamous epithelial cells, including skin or some mucosal epithelial cells. There are more than 120 HPV subtypes in nature, at least 40 of which primarily infect the mucosa of the human genital tract, and at least 15 of which have been identified as being associated with cervical cancer. At least 75% of women who are sexually active will become infected with HPV at some point in their lives, especially in their 20s and 30s, but 80-90% of women can clear the virus naturally. Only a very small percentage will have persistent HPV infection. 2, HPV virus test report form frequently asked questions in the HPV virus test report form, often see the high-risk type of virus type, low type of virus type, is divided as follows: persistent infection of the cervix, resulting in cervical cancer of such subtypes is called high-risk type, there are 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68; and only cause The ones that cause only benign genital warts (condyloma acuminata) are called low-risk types, and there are subtypes 6, 11, 42, 43, 44, etc. Whether HPV infection necessarily leads to cervical cancer or not, there are two outcomes of HPV infection: first, the body clears the virus; second, the virus infection persists – cervical epithelial atypical hyperplasia – cervical cancer. -cervical cancer. Therefore, it is not certain that the infection will develop into cancer if it exists. Meanwhile, it usually takes more than 10 years to develop from cervical epithelial atypical hyperplasia to cervical cancer. Therefore, intervention treatment at any stage of persistent viral infection or cervical epithelial atypical hyperplasia will not develop into cervical cancer. At present, although there are no anti-viral drugs, drugs such as interferon or Chinese medicine Povidon are scientifically proven to improve the local immunity of the cervix and help the body to clear the virus.
