What is cervical pre-lesion?

Clinically, many cervical diseases are serious conditions. Because cervical diseases, if not treated and controlled in time, are likely to develop into malignant diseases, which is what we often call malignant diseases. Such situations cannot be ruled out as being caused by cervical precancerous lesions, so it is necessary to have a certain understanding of this type of situation and take preventive measures. So what does cervical precancerous lesions mean?

The so-called precancerous lesions refer to the fact that the lesions themselves are not cancer and do not necessarily turn into cancer, but on the basis of these lesions, under appropriate conditions, they may turn into cancer. In order to block the development towards cancer, we need to understand some basic knowledge.

In the past, early changes of cervical cancer were considered to be cervical erosion, polyps, ruptures, and eversions. However, it is now believed that it is necessary to judge from the pathological histological changes of cervical biopsy. If intestinal metaplasia is found in the squamous epithelium of cervical puncture biopsy, it is called early cancer. The cervical surface of many patients is smooth, but microscopic examination shows moderate to severe intestinal metaplasia. This requires great attention in the investigation work, especially the attention of medical staff at the grassroots level in rural areas is very important.

Observing the formation and development of cervical cancer tissue, it can be seen that there is cervical squamous cell metaplasia in the physiological gene mutation; in the active metaplasia process, the addition of some foreign carcinogens can cause the active immature cells or proliferating squamous epithelial cells to develop in the direction of intestinal metaplasia. At this time, the squamous epithelial cells can be different from normal cells, but cannot be diagnosed as cancer. Although not all intestinal metaplasia will develop into cervical cancer, according to studies, if left untreated, 10% to 15% of mild, mild-to-moderate and 75% of moderate-to-severe intestinal metaplasia may develop into invasive cancer.

Anyone with early cervical cancer should be given immediate treatment, such as laser, refrigeration, electrocautery, cone biopsy and other methods. However, for patients whose pathological puncture biopsy shows moderate to severe intestinal metaplasia, due to the high possibility of lesions, hysterectomy should be considered, and regular follow-up is required after surgery to prevent recurrence or misdiagnosis.
