Low-grade intraepithelial neoplasia is a mild degree of intraepithelial neoplasia, which is generally not precancerous, but needs to be observed regularly to prevent its malignant transformation.
Intraepithelial neoplasia refers to abnormal lesions of epithelial tissue, with heterogeneous hyperplasia. The proliferating cells usually vary in size, morphology and arrangement, but generally the heterogeneous cells do not exceed 2/3 of the epithelial layer. low-grade intraepithelial neoplasia is less severe in heterogeneous hyperplasia, but if it continues to develop, it may have a tendency to become cancerous, and needs to be closely observed.
In clinical practice, intraepithelial neoplasia is categorized into low-grade and high-grade. Low-grade intraepithelial neoplasia generally refers to mild or moderate heteroplasia, while high-grade intraepithelial neoplasia refers to severe heteroplasia or carcinoma in situ.
