Renal tumor can be initially judged by CT and other imaging examinations, and clearly diagnosed by puncture biopsy, it is recommended to go to the hospital for further examination in time.
Generally speaking, it can be initially judged by CT and other imaging examinations. Malignant tumors are mostly solid tumors with rapid growth, no obvious boundary, no complete envelope, and internal calcification. Benign tumors are mostly cystic, slow-growing, with intact periphery and clearer borders.
The benign tumors have no obvious changes in the enhanced CT examination, while the malignant tumors will have obvious enhancement, and at the same time, if the tumor is large, it can also have liquefaction necrosis in the internal manifestation.
In addition, puncture of tumor tissue and pathological examination of tissue section are the gold standard for determining the benign or malignant nature of renal tumors.
