Clinically, the causes of cervical cancer include the following aspects:

First, the incidence of cervical cancer significantly increases in women who start sexual activity at an early age or have multiple sexual partners.

Second, genetic factors also play a certain role in the development of cervical cancer.

Third, the female population with malnutrition or chronic inflammatory diseases of the cervix can also lead to a high incidence of cervical cancer.

Fourth, women with sexually transmitted diseases, such as gonorrhea and genital warts, can also cause cervical cancer.

Fifth, some women with viral infections may also undergo carcinogenic changes in the cervix, thus forming cervical cancer.

Early symptoms of cervical cancer

The most common early symptom of cervical cancer may be contact bleeding, including vaginal bleeding after intercourse. However, not many patients exhibit these symptoms. Many patients do not show any symptoms, but there are some pathological changes on the cervix. Therefore, it is recommended that women who are sexually active should undergo regular early screening for cervical cancer, including HPV, TCT, and colposcopy examinations. Regular checks can determine whether there are indeed pathological changes on the cervix. This is also a preventive measure for women, and the screening is highly efficient at detecting early pathological changes in the cervix.

Cervical cancer screening

For the examination of cervical cancer, it should be based on medical history and clinical manifestations, especially for people with contact vaginal bleeding, a detailed general examination and gynecological examination should be conducted, and an examination of cervical biopsy tissue is needed for diagnosis. What specific examinations are there? There are cervical scrape cytology tests, iodine tests, colposcopy, examination of cervical and cervical canal tissue, as well as post-surgical cervical conization, and examination of postoperative specimens. Therefore, there are indeed many examinations, including some radiological assessments such as enhanced CT, PADCT, MRI, and other such tests.

Why would someone get cervical cancer?

Why does cervical cancer occur? There are several reasons for cervical cancer: The first is infection with the human papillomavirus, also known as HPV infection, which is the fundamental cause of precancerous lesions and cervical cancer. Secondly, there are other factors; in a few cases, HPV DNA is not detected in the tumor tissue, especially among elderly patients, and it is related to early childbirth and multiple pregnancies. The third point is that cervical cancer incidence is associated with high-risk males, including those who have had penile cancer, prostate cancer, or are high-risk individuals for cervical cancer. Women who are in contact with these high-risk men are more likely to develop cervical cancer. Lastly, irregular diet and lifestyle, along with smoking and drinking, can suppress the body's immune function, potentially promoting cancer.

What is cervical cancer?

Cervical erosion is one of the most common malignant gynecological tumors, belonging to a type of cervical cancer. Cervical cancer itself is a significant branch within this category, and both the incidence and mortality rates of cervical cancer are relatively high in our country. However, recent advances in medical science have led to a noticeable decline. Cervical cancer is associated with HPV (Human Papillomavirus) infection, as well as with early childbirth, multiple pregnancies, and smoking. The definitive diagnosis of cervical cancer relies on the examination of cervical and endocervical canal live tissues, colposcopic biopsy, or cervical scrape cytology. Typically, after CT, MRI, or other imaging studies, a mass may be detected. Possible symptoms of cervical cancer include vaginal bleeding and vaginal discharge.

Precursors of cervical cancer

The occurrence and development of the cervix is a process from quantitative to qualitative change, evolving gradually to a sudden shift over a long period. The precursor might be the heterotypic zone of the cervix, which is a common site for abnormalities. During the formation of this heterotypic zone, cervical epithelial metaplasia is relatively active, and, compounded by infection with the human papillomavirus and further stimulated by external carcinogens, immature or proliferative squamous epithelial cells may exhibit gradual changes or atypical hyperplasia, potentially leading to sarcomatoid changes in the cervical epithelium. This might be a precursor sign.
