1.Local cervical lesions: early marriage, early childbirth and multiple births cause local trauma to the cervix, cervical erosion, cervical polyps, cervical lacerations and precancerous lesions of the cervix are intrinsic factors leading to the development of cervical cancer 2.Sexuality factors: cervical cancer can be said to be an infectious disease in a sense low age of first intercourse, multiple sexual partners, frequent sex life with multiple or cervical cancer-afflicted sexual partners, lack of attention to sexual hygiene, etc. Inadequate attention to sexual hygiene, etc. All of them can lead to certain viruses, such as human papilloma virus (HPV) herpes virus type II (HSV-II), and chlamydia bacteria to enter the reproductive tract and repeatedly infect the erosion surface of the cervix to induce cervical cancer. The risk of cervical cancer in the wife of a man who has prostate cancer of the penis or whose ex-wife has had cervical cancer is several times higher than that of other women. Human papillomavirus (HPV) infection: In recent years, HPV infection has been found to be a major risk factor for cervical cancer. More than 70 types of homologous HPV have been identified, of which more than 20 exist in the human genital tract and can be divided into three groups according to their carcinogenic risk. The following four causes of cervical erosion are: 1. premature sexual activity, too many partners: most young people now have premarital intercourse, premature sexual life, frequent change of sexual partners and excessive intensity of sexual life, are causes of cervical erosion that cannot be ignored. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. 3, multiple abortions: too much pregnancy from premarital sex leads to multiple abortions, diagnostic scraping, cervical dilatation and other gynecological procedures, all of which may occur cervical damage or inflammation and finally lead to cervical erosion. 4, excessive cleaning: now there are many women’s cleansing products on the market, if you choose improperly, using a large concentration of disinfectant solution to rinse the vagina, will not only lead to vaginal pH imbalance affecting the growth of normal vaginal flora, so that its role in inhibiting germs is reduced, resulting in different degrees of cervical epithelial damage and celiac disease.
