What are the causes of cervical precancerous lesions? There are 4 main causes of cervical precancerous lesions

Gynecologists point out that cervical cancer is one of the common malignant tumors in women and is the only cancer that has been found to have a cure so far. Cervical cancer is caused by human papillomavirus (HpV), which can be directly transmitted through skin contact and has a latent period of more than ten years. Therefore, there are no symptoms in the early stages. Cervical cancer can be prevented and measured. Timely screening for cervical cancer can effectively avoid misfortune. Cervical cancer has no direct connection with sexual life, and women need to have a correct understanding of it. Due to the misunderstanding of the concept of cervical cancer pathogenicity, it seems that cervical cancer is synonymous with uncleanliness, which brings great harm to women, so that they are unwilling to face this problem and lead to misfortune.

About 200,000 women die from cervical cancer worldwide. In developing countries, cervical cancer is a common gynecological tumor, ranking first. There are 13 new cases found in China every year. Shanxi is the region with the highest mortality rate, and Tibet is the region with the lowest mortality rate. Cervical cancer refers to a tumor that occurs in the vagina.

The general trend is that rural areas are higher than urban mountainous areas and plains. According to reviews and surveys of provinces, cities and autonomous regions, the mortality rate of cervical cancer in my country ranks first among all cancer mortality rates. As for the metastasis of cervical cancer, it can spread directly to adjacent tissues and organs, downward to the vaginal vault and vaginal wall, and upward to invade the uterus, pelvic tissues, bladder, and rectum. Lymph nodes can also be metastatic to the cervical, internal iliac, external iliac, and inguinal lymph nodes through lymphatic vessels, and can even be metastatic to the clavicle and other lymph nodes throughout the body. Blood metastasis is relatively rare, and common sites of metastasis are the lungs, liver, and bones. Three months after the onset of cervical cancer symptoms, two-thirds of patients have advanced cancer.

Four major causes of cervical precancerous lesions

Many women are very afraid of cervical cancer, but few know how to prevent it correctly. However, with the improvement of social living standards, people's awareness of cervical cancer prevention and treatment has become more and more prominent.

One is bleeding after sexual intercourse. ~80% of cervical cancer patients have this symptom;

Second, contact bleeding, bleeding after sexual intercourse, or uterine bleeding after a gynecological consultation are signs of cervical precancerous lesions;

Third, young women with cervical erosion who have not been treated for a long time, or who still have cervical erosion after menopause, should pay attention to it;

Fourth, there is mixed blood in the leucorrhea. In addition to uterine bleeding caused by IUD insertion, women with mixed blood in their leucorrhea for a long time should be checked in time.

According to medical statistics, about 15% of patients with cervical precancerous lesions will develop into cervical cancer. It takes about 10 years for precancerous lesions to develop into cancer. Patients with cervical precancerous lesions have time to receive effective treatment. 80% of cervical precancerous lesions can be treated through early detection and treatment. Therefore, women are reminded to do physical examinations to prevent problems before they occur.
