There are several types of cervical precancerous lesions

The onset of cervical cancer is not a matter of one day or one night. It is mainly caused by the patient's bad living habits. Experts say that from a clinical point of view, cervical precancerous lesions go through three levels. What are the three levels? Let us learn about the three levels of cervical precancerous lesions, hoping to help you fully understand cervical cancer.

In fact, there are three outcomes for cervical precancerous lesions, namely, spontaneous regression (or reversal), persistence (or lesion stability), and progression (or canceration). The risk of progression of cervical precancerous lesions of grade I, II, and III is 15%, 30%, and 345% respectively. The risk of cervical precancerous lesions of grade I, II, and III progressing to cervical cancer is 4 times, 14.5 times, and 46.5 times the normal risk respectively.

Therefore, attention should be paid to those above level II, and among the factors related to prognosis, high-risk HPV infection is the main factor for cervical cancer. The risk of cervical lesions progression in patients with persistent high-risk HPV infection is 6.46 times that of low-risk. The relative risk of cervical cancer is 250 times that of normal women. Patients with cervical precancerous lesions level I and negative HPV infection have a one percent lower chance of canceration, and 2/3 of the cases can regress naturally.

It is observed that the natural evolution of cervical precancerous lesions to cancer generally takes about 10 years. It does not necessarily progress in sequence and the time may be shortened. However, with age, the reversal rate of cervical precancerous lesions gradually decreases, especially for HPV-positive patients, so they should be checked and treated immediately.

Currently, patients with cervical precancerous lesions I and negative HPV infection can be observed for 6 to 12 months and re-examined with TCT (membrane-based ultra-thin cytology test), or can undergo physical therapy; patients with cervical precancerous lesions I and HPV-positive and cervical precancerous lesions II can undergo Leep knife circumcision; patients with cervical precancerous lesions III can be hospitalized for cone biopsy, and the cone biopsy specimen can be sent to pathology, and the next step of treatment will be carried out based on the pathological diagnosis.

The above is the introduction to the three levels of cervical precancerous lesions. I believe you have a certain understanding of them.
