Low grade is an indicator for describing the degree of malignancy of a tumor. Low grade indicates that the tumor is better differentiated, the degree of malignancy is relatively low, and the lesion is early.
Tumor differentiation means that the higher the degree of similarity between the tumor and normal tissue in terms of structure and function, and the more the tumor still has certain normal functions, the higher or better the degree of differentiation is, on the contrary, the lower the degree of differentiation is, the worse the differentiation is.
According to the degree of differentiation of the tumor, the tumor can be graded to describe its malignant degree, and the three-level grading method is more often used, with grade I being highly differentiated, grade II being moderately differentiated, and grade III being poorly differentiated.
For some tumors, a two-level grading method is generally used, i.e., low-grade and high-grade, with low-grade representing better differentiation, such as cervical biopsy, which suggests low-grade squamous intraepithelial lesions, often indicating precancerous cervical lesions.
Although low grade represents early lesions with low differentiation, it needs to be treated as early as possible, and it is recommended to consult a doctor in time and standardize the treatment under the guidance of a professional doctor.
