Introduction to the main risk factors of cervical cancer

The true cause of cervical cancer is still unknown, but there is a lot of data showing that the occurrence of cervical cancer is likely to be the result of a combination of factors. The main and important predisposing factors are as follows.

Early sexual life and disordered sexual life : The occurrence of cervical cancer is closely related to sexual life. Women who have sexual life at an early age are more likely to get cervical cancer.

Cervical erosion, laceration and eversion : If a woman suffers from cervical erosion, the incidence of cervical cancer is 2-7 times higher than that of women without cervical erosion. If a woman suffers from severe cervical erosion, the incidence of cervical cancer is 9 times higher than that of women with moderate erosion.

Smegma irritation : Among ethnic and religious groups that have the custom of routine circumcision of male infants, such as Jews and Muslims, women have a low incidence of cervical cancer.

Viral infection : In recent years, three viruses have been found to be related to the incidence of cervical cancer, namely human herpes virus type 2, human papillomavirus and human cytomegalovirus.

Excess estrogen : Estrogen can stimulate the proliferation of cervical epithelium. Excess estrogen can cause significant proliferation of cervical epithelium and even cancer. In view of this, some scholars believe that excess estrogen may induce cervical cancer.
