What does low-grade malignant tumor mean?

Malignant tumors can be divided into low, moderate and high malignant according to the differentiation degree of tumor cells. The better the differentiation degree of tumor cells, the higher the differentiation degree, indicating that the morphology and function of tumor cells are closer to normal cells, indicating that the malignant degree of tumor is relatively low, belonging to low malignant tumor, the possibility of recurrence after tumor surgery is small, and the survival time is relatively long. If the patient belongs to a highly malignant tumor, it means that the tumor cell differentiation is poor, the biological function and morphology are far different from normal cells, the malignant degree is very high, and it is easy to show recurrence and metastasis in a short period after surgery.
