Giving birth to a fetus can lead to high incidence of cervical cancer

Cervical cancer is a common female disease with a high incidence rate. What are the causes of cervical cancer ? Generally speaking, women with disordered sex life, early marriage and multiple births are more likely to develop cervical cancer. Let's take a look at the causes of cervical cancer.

· For delivery of a fetus, cervical dilation is a necessary and sufficient condition.

The fetus can only be delivered when the cervix gradually expands with labor pains until it is wide enough to pass the largest part of the fetus' head, which usually takes 10 hours. After cervical laceration, the resistance of local tissues decreases in mild cases, which is prone to infection or even mutation. In severe cases, it causes heavy bleeding at the time, and the internal os function is incomplete later, which is prone to miscarriage and premature birth.

The histological factors of the cervical opening are the important reasons for the high incidence of cervical cancer.

The squamous epithelium of the cervicovaginal part is continuous with the squamous epithelium of the vagina, and the cervical canal is columnar epithelium, and the two are transitioned at the cervical opening. The cervicovaginal mucosa, like the vaginal mucosa, is a stratified squamous epithelium, which is corrosion-resistant and periodically exfoliated, and has strong self-defense capabilities. The endometrium of the cervical canal is a single-layer columnar epithelium, which not only has poor anti-infection capabilities, but also constantly transitions under the influence of estrogen. Women's estrogen levels change throughout their lives, with high levels during puberty and pregnancy and low levels in girls and the elderly. These changes will affect changes in the cervical mucosa.

Through the experts' introduction to the causes of cervical cancer, I believe everyone has already understood it. Experts remind that if you are sick, you must seek medical treatment in time to avoid adverse consequences. If you still have questions about the causes of cervical cancer, you can contact online experts or call the hotline.
