What are the manifestations of cervical precancerous lesions? What are the causes of cervical precancerous lesions?

In the eyes of cervical cancer patients, there are no symptoms in the early stage, so it cannot be found. The important thing is to treat the symptoms in the late stage. Almost everyone is unfamiliar with cervical precancerous lesions. Therefore, in order to let you know the symptoms of the disease, the following content introduces the disease in detail.

1. Performance

Bleeding after sex.

70%-80% of cervical cancer patients have this symptom.

Cervical erosion.

Young women with cervical erosion that has not been treated for a long time, or who still have cervical erosion after menopause, should pay attention to it.

Bleeding after contact, bleeding after sexual intercourse, or uterine bleeding after a gynecological examination are all signs of cervical precancerous lesions.

4. In addition to uterine bleeding caused by IUD insertion, women with long-term leucorrhea mixed with blood should be checked in time.

2. Reasons

1. Improper sexual life: Women who do not have sexual life usually do not get cervical cancer. The earlier you have sexual life, the more likely you are to get cervical cancer in the future, which is also an important cause of cervical precancerous lesions.

2. High-risk human papillomavirus (HpV) infection: It is the main factor leading to cervical precancerous lesions. More than 90% of cervical cancer patients are accompanied by high-risk HpV infection. When HpV infection continues to exist, it can induce cervical cancer under the influence of factors such as smoking, use of contraceptives, and sexually transmitted diseases.

3. Cervical inflammation and abnormal hormone secretion: If there is long-term cervical damage, skin rupture, erosion, and inflammation, it can be transformed into early cervical cancer cells. Surveys show that abnormal progesterone secretion can change the stability of cervical epithelial cells, leading to abnormal changes and the development of cervical cancer cells.

4. Smoking: Smoking increases the chance of cervical cancer because it reduces the body's immunity and accelerates the development of cervical cancer cells. In addition, some carcinogens produced by smoking may also lead to the development of cervical precancerous lesions.
