Is cervical intraepithelial neoplasia grade 3 cancer?

Cervical intraepithelial neoplasia grade 3 (CIN3) refers to severe cervical epithelial dysplasia. It is generally not cancer, but rather a precancerous condition. The detailed analysis is as follows:

Cervical intraepithelial neoplasia is a general term for precancerous lesions closely associated with invasive cervical cancer, including cervical atypical hyperplasia and cervical carcinoma in situ. CIN3 indicates a more advanced stage of lesion development; although it has not yet progressed to cancer, it is considered a precancerous condition. If appropriate and standardized treatment is not promptly administered, the lesion may progress to invasive cancer, such as cervical squamous cell carcinoma or cervical cancer.

After being diagnosed with CIN3, patients are advised to promptly visit the obstetrics and gynecology department of a hospital and undergo surgical excision under the guidance of a physician.
