Does repeated abortion lead to cervical carcinoma in situ? What are the causes of cervical carcinoma in situ in women?

A young woman was unexpectedly diagnosed with cervical carcinoma in situ during a pre-pregnancy checkup. The reason was that she had improper contraception and had undergone four early pregnancy termination surgeries. Experts pointed out that repeated termination of pregnancy is one of the risk factors for cervical malignant lesions. Frequent surgeries have repeatedly damaged the originally healthy cervix. At the same time, receiving surgery in an informal small clinic will greatly increase the chance of being infected with human papillomavirus (HpV).

In life, many women of childbearing age do not know how to take scientific and reasonable contraceptive measures, and choose painless termination of pregnancy after an unexpected pregnancy. What's more, some women start having sex before one month after the operation. Little do they know that having sex too early after the operation is prone to bacterial or viral infection, causing chronic cervicitis and increasing the chance of malignant transformation. For this reason, Zhang Jiong reminds female friends to take scientific and reasonable contraceptive measures; pay more attention to anti-inflammatory and care after gynecological surgery.

In addition to repeated abortions leading to cervical carcinoma in situ, what other factors can induce cervical carcinoma in situ?

1. Some people believe that the wife of a husband with phimosis or foreskin is at a higher risk of cervical cancer. The wife of a man with penile cancer or prostate cancer or whose ex-wife has cervical cancer, or a man with multiple sexual partners, has a higher chance of cervical cancer. Therefore, this is one of the causes of cervical cancer.

2. Pathogen causes. Many pathogens are closely related to cervical cancer, especially human papillomavirus (HpV), herpes simplex virus-2 (HSV-2), human cytomegalovirus (HCMV), Chlamydia trachomatis (CT) and Epstein-Barr virus (EBV).

3. Virus or fungal infection is also a cause of cervical cancer. Herpes simplex virus type II, human papillomavirus, human cytomegalovirus and fungal infection may be related to the occurrence of cervical cancer. However, which virus is the main cause or which viruses work together to easily cause cervical cancer has not yet been resolved.

4. Sexual promiscuity and sexually transmitted diseases. Some surveys and studies have shown that sexual promiscuity plays an important role in the etiology of cervical cancer. Those who start sexual life before the age of 15 or have more than 6 sexual partners have a 10-fold increased risk of cervical cancer. Male sexual promiscuity also increases the risk of cervical cancer in their spouses.

5. Marriage and childbearing reasons. Sperm is one of the causes of cervical cancer. Semen has a strong mutation-promoting effect on the squamous epithelium of the cervix, especially for adolescent women. The cervical epithelium is in a highly sensitive period, and the inducement of semen is more dangerous. In addition, according to epidemiological surveys, only 10% of nulliparous women suffer from cervical cancer; the early age of first childbirth has a high incidence of cervical cancer. This may be related to the fact that women's cervix is ​​prone to tearing and damage during childbirth, and the immune function is low during pregnancy, which makes the cervical epithelial cells susceptible to invasion by external pathogenic factors. Therefore, parity also has a certain impact on the occurrence of cervical cancer.

6. Cervical erosion, laceration and eversion can also lead to a high incidence of cervical cancer. Due to the physiological and anatomical reasons of the cervix, it is easily stimulated by various physical, chemical and biological factors, including trauma, hormones and viruses. This is also the cause of cervical cancer.

7. Smoking: Epidemiological surveys in recent years have shown that smokers have a 2-fold increased risk of cervical cancer. Smoking strengthens the HPV infection factor, and the amount of smoking is positively correlated with the risk of cervical cancer.
