Complicated renal cyst is a tumor?

Complex renal cysts are not tumors. Complex renal cysts are a general term for a series of renal lesions that distinguish simple renal cysts from simple renal cysts, including hemorrhagic cysts, calcified cysts, compartmentalized cysts, cysts with infection, parapelvic cysts, and cysts of unknown diagnosis. Kidney tumor is a general term for a large class of kidney tumors. Kidney tumors account for about 2%-3% of all human tumors. Of course, kidney tumors also include benign tumors and malignant tumors. The most common benign tumors of kidney include hamartoma, renal hemangioma, renal adenoma, and proximal glomerular cell tumor. Renal malignant tumors are mainly renal cell carcinoma, blastoma, and renal pelvis cancer.
