Cervical cancer is one of the common malignant tumors in women and has a high incidence rate in China, which may be related to factors such as early marriage, early childbirth, multiple births and sexual disorders among women, and associated with HPV infection. 1.Age: The occurrence of cervical cancer has a certain relationship with age. Women under 35 years old have a low probability of cervical cancer, while the incidence of cervical cancer is high between 35-59 years old and decreases after 60 years old. There is a trend of younger age in recent years. It is closely related to HPV infection, and persistent infection may lead to precancerous lesions and progress to cancer. 2. Those who marry early and have more children: The report of Beijing Cervical Cancer Prevention and Control Collaborative Group shows that the prevalence rate of women who marry before the age of 20 is three times higher than those who marry between 21 and 25, and seven times higher than those who marry after the age of 26. Moreover, the more births there are, the higher the chance of cervical cancer. 3.Multiple sexual partners: According to a study in the United States, the number of sexual partners ≥10 accounts for 36% of the new cases of cervical cancer because spermatozoa enter the vagina and produce a kind of sperm antibody, which usually disappears completely in about 4 months. If there are many sexual partners and frequent intercourse, multiple antibodies and heterosexual proteins will be produced, which will make them more prone to cervical cancer. 4.Patients with cervical atypical hyperplasia: especially those with moderate and severe atypical hyperplasia are likely to be transformed into cervical cancer if they are not treated actively.
