Kidney cancer

Renal tumors are more common in urinary tumors, second only to bladder tumors. Most primary renal tumors are malignant, including renal cell carcinoma, Wilms tumor, and renal pelvis cancer. Benign tumors of the kidney include renal adenomas, vascular smooth muscle lipomas, hemangiomas, lipomas, fibroids, and juxtaglomerular cell tumors. Renal cancer is also called renal cell carcinoma, renal adenocarcinoma, clear cell carcinoma, renal parenchymal carcinoma, etc. Renal parenchymal carcinoma is adenocarcinoma derived from renal tubular epithelial cells, 85% of which are clear cell carcinoma, and some are granular cell carcinoma and mixed cell carcinoma.
