The causes of cervical cancer (i.e. cervical cancer) are still unclear. A lot of data from home and abroad confirm that women with early marriage, early childbearing, multiple births and disordered sexual life have a higher prevalence. It is also believed that the cholesterol in circumcision can be transformed into carcinogenic substances after the action of bacteria, which is also an important cause of cervical cancer. Relationship with sexual life and marriage The incidence of cervical cancer is four times higher in women who have early sexual life (meaning having sex before the age of 18) than in those who start to have sex after the age of 18. The incidence of cervical cancer is 6 times higher in women with early sex and sexually transmitted diseases such as syphilis and gonorrhea than in normal women. It has been confirmed that if women have sex with more than one man, they have more chances of cervical cancer, while virgins rarely suffer from cervical cancer. Unmarried and unborn women have very little chance of developing cervical cancer, and the incidence of cervical cancer is also higher in multiple marriages. Multiple births with poor perinatal maintenance and delivery procedures also increase the incidence of cervical cancer. However, multiple births do not result in increased incidence of cervical cancer. Socioeconomic status and smoking Cervical cancer occurs mostly in women with low socioeconomic status. Women who smoke are two times more likely to develop cervical cancer than non-smokers. In addition, different living habits in different regions may also affect the incidence of cervical cancer, and women with low immune function and poor mental factors are all related to the occurrence of cervical cancer.
