Kidney tumor is benign or malignant.

How to judge whether a kidney tumor is benign or malignant is mainly based on the pathological examination after surgery, because the pathologist is the doctor's doctor, and the pathological diagnosis is the most accurate examination result. Therefore, only after the whole tumor is completely cut off, all the excised masses are sent to the pathology department for laboratory tests. After the sections are made, the pathologist observes under the microscope whether it is benign or malignant, and which pathological classification is malignant. This is the most accurate judgment result. Before surgery, it can only be inferred whether it is benign or malignant according to the kidney enhanced ct or kidney enhanced magnetic resonance imaging. If there is a lot of fat density in the tumor, it may be judged that there is a benign renal tumor, that is, renal angiomyolipoma. If the kidney is malignant, the performance is different. Therefore, it is mainly judged based on imaging before surgery.
