What are the cervical precancerous lesions? What are the triggering factors of cervical precancerous lesions?

Cervical cancer is one of the most common malignant tumors in women, and its cause is still unclear. Women who marry early, give birth prematurely, have multiple births, and have sexual dysfunction have a higher incidence of the disease. There are no symptoms in the early stages, but vaginal bleeding is abnormal in the later stages. The current treatment options are mainly surgery and radiotherapy, and a combination of Chinese and Western medicine can also be used, but the cure rate for patients in the middle and late stages is very low. As a woman, you should clean yourself, strengthen your health care, pay attention to regular gynecological examinations, and seek medical attention in a timely manner when you find symptoms or signs.

Although the cause is still unclear, epidemiologists have found that some factors are closely related to the incidence of cervical cancer, which we call risk factors. So what are the factors that promote cervical precancerous lesions?

1. Relationship with sex life and marriage

Women who start sexual life early and have sexually transmitted diseases such as syphilis and gonorrhea have a 6-fold higher incidence of cervical cancer than normal women. It has now been confirmed that if women have sex with multiple men, they have a greater chance of developing cervical cancer, while virgins rarely develop cervical cancer. Unmarried and nulliparous women have a low chance of developing cervical cancer, and the incidence of multiple marriages is also high. Multiple births, perinatal maintenance, and poor delivery processes can also increase the incidence of cervical cancer. However, multiple births do not increase the incidence of cervical cancer.

2 Spouse Relationship

The risk of cervical cancer is relatively high for wives whose husbands have foreskin that is too long or phimosis. The risk of cervical cancer increases for wives whose husbands have penile cancer, prostate cancer or ex-wife cervical cancer, and who have sexual partners.

3. Viral or fungal infection

Herpes simplex virus type II, human papillomavirus, human cytomegalovirus, and fungal infections may be associated with the occurrence of cervical cancer. However, which virus mainly induces or under which virus coordination is prone to cervical cancer has not been resolved.

4. Socioeconomic status and smoking

Cervical cancer usually occurs in women with lower social and economic status. Women who smoke are twice as likely to develop cervical cancer as non-smokers. In addition, different living habits in different regions may also affect the incidence of cervical cancer. Women's low immune function and bad mental factors are related to the occurrence of cervical cancer.

5. Estrogen can promote the growth of uterine and vaginal tissues and stimulate cervical epithelial hyperplasia

Some people have used estrogen diol benzoate alone to induce cervical cancer in mice. Animal experiments have also shown that estrogen has a promoting effect on cervical cancer in mice induced by carcinogens such as methylcholanthrene. When Yu Mingpeng studied the hormone metabolism of cervical cancer patients, he found that the ratio of estradiol, estrone and estriol in the urine of patients with carcinoma in situ and early cervical cancer was high.

Estrogen levels during pregnancy are 25 to 40 times higher than those during non-pregnancy, which can significantly proliferate the cervical epithelium, even similar to atypical hyperplasia or carcinoma in situ, but gradually return to normal after delivery.

6. Cervical erosion

"What behaviors in daily life may cause uterine disease?" She thought for a moment and said seriously, "The uterus is a reproductive organ related to sex and pregnancy. For example, in artificial abortion, doctors can only perform surgery based on feelings and experience, so the uterus may be damaged or some mistakes may occur, leading to some complications such as heavy bleeding, uterine perforation, uterine adhesions, etc. If heavy bleeding and uterine perforation are serious, the uterus needs to be repaired or even removed. Uterine adhesions can lead to infertility, and pregnancy and childbirth can cause cervical lacerations. Although cervical lacerations sometimes have small wounds and do not cause any symptoms at the time, it opens a convenient door for bacteria, leading to cervical inflammation in the future. Unclean sexual life can easily cause vaginitis and may lead to cervical erosion, and long-term cervical erosion is closely related to cervical cancer."

The editor reminds online: The cure rate of patients with mid- to late-stage cervical cancer is very low. As women, we should clean ourselves, strengthen health care, pay attention to timely gynecological examinations, discover symptoms and signs, and seek medical treatment in time.
