Will bleeding after sexual intercourse lead to cervical cancer? What are the methods for diagnosing cervical precancerous lesions?

What are cervical precancerous lesions? The occurrence and development of cervical cancer has a gradual evolution process, which can take from a few years to several decades. Let Xiaobian introduce it in general.

What are cervical precancerous lesions?

Cervical precancerous lesions refer to cancerous lesions caused by lesions before cancer occurs. Cervical precancerous lesions are atypical hyperplasia of the cervix. The occurrence and development of cervical cancer has a gradual evolution process, which can take from a few years to decades. It is generally believed that this evolution process has gone through several stages such as hyperplasia, atypical hyperplasia, carcinoma in situ, early invasion and invasive cancer.

Symptoms of cervical precancerous lesions:

Bleeding after sexual intercourse. 70%-80% of cervical cancer patients have this symptom.

2. 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.

Diagnosis of cervical precancerous lesions:

1. Cervical Pap smear method: For the traditional cervical cytology examination, its widespread application has successfully reduced the incidence and mortality of cervical cancer by about 70% in the past 50 years. However, due to the false negatives and high missed diagnosis rate of Pap smear, it no longer meets the needs of today's medical services and is gradually replaced by more advanced examination methods.

2. TCT thin-layer liquid-based cervical cytology: It is a new cytology technology invented in the late 1990s. It can significantly improve the detection rate of cervical cancer and precancerous lesions. It is the most widely used cervical cytology examination method in the world.

What are the early symptoms of cervical cancer?

1. Since the early symptoms of cervical cancer are generally non-specific and cannot be diagnosed based on symptoms and signs alone, cervical cancer patients should go to the hospital for a detailed examination when they have symptoms.

2. The early symptoms of cervical cancer mainly include vaginal bleeding. The earliest cervical cancer can manifest in women of any age, especially before and after menopause, with a small amount of intermittent irregular bleeding, increased bleeding in the late stage, and even fatal massive bleeding caused by erosion of large blood vessels.

3. Vaginal discharge, the initial amount is not much, and there is no odor. But as the cancerous tissue of cervical cancer ruptures, serous secretions can flow out, and cervical cancer patients will have odor. When the adjacent tissues of cervical cancer are obviously infiltrated, involving the pelvic wall, obturator nerve, lumbar nerve, etc., severe and persistent lumbar or sciatic nerve pain will occur. People find the early symptoms of cervical cancer better early.
