Several major causes of cervical cancer

Cervical cancer is a common gynecological malignancy. The incidence rate in China is very high. It is a gynecological disease that many women fear. It is necessary to understand the causes of cervical cancer so that it can be discovered and treated in time. So what are the causes of cervical cancer ? The following is a detailed answer from relevant experts.

(1) Sexual life, marriage, and pregnancy factors

Women who have sex too early (before the age of 18) have a 4-fold higher incidence of cervical cancer than those who start sex after the age of 18. If women start sex early and have sexually transmitted diseases such as syphilis and gonorrhea, their incidence will be 6-fold higher than normal women. It has been confirmed that women who have sex with multiple men have a higher chance of developing cervical cancer. This may be because the lower reproductive tract of prepubescent women is not yet mature and is more sensitive to the stimulation of carcinogenic factors. If they start sex early, they are more likely to develop cancer once they are infected by certain bacteria or viruses.

(2) Exogenous factors

The incidence of cervical cancer among Jews is low. Research suggests that the reason may be related to the Jewish custom of removing the foreskin of male babies after birth. However, some believe that among Jewish women who have not removed the foreskin, cervical cancer is also rare. There is currently a lack of experimental data to prove that circumcision can reduce the incidence of cervical cancer, although Nahmos has isolated HSV-2 from the smegma of men.

(3) Endocrine factors

Whether sex hormones promote the occurrence of cervical cancer has also been a topic of research for many years. Animal experiments have successfully used estrogen to induce squamous cell carcinoma in mice, but there is no conclusive evidence that exogenous estrogen can induce cervical cancer in humans.

(4) Sexually transmitted diseases

Before the 1960s, it was believed that the incidence of cervical cancer was high in patients with syphilis, but direct evidence that syphilis causes cervical cancer has not yet been found. Trichomonas vaginitis often coexists with cervical precancerous lesions or cervical cancer. Parfen et al. found that patients with atypical cervical hyperplasia and Trichomonas vaginitis have an increased chance of transformation into invasive cancer, and have successfully infected animals with Trichomonas to induce cervical cancer. However, both are sexually transmitted diseases and can coexist, and the vaginal pH of patients with atypical cervical hyperplasia is often alkaline, which is conducive to the growth of Trichomonas, so it cannot be confirmed that Trichomonas infection is also the cause of cervical cancer.

The above is an introduction to the causes of cervical cancer. I believe everyone should have a certain understanding of cervical cancer. If you want to know more about cervical cancer, please consult online experts.
