Introduction to
Kidney Cancer
Kidney cancer, or cancer of the kidney, is any type of cancer that has arisen from the kidney. Kidney cancer does not usually include a cancer that arose outside the kidney and metastasized to include metastatic cancer of the kidney.
The most common types of kidney cancer include renal cell carcinoma and urothelial cell carcinoma of the renal pelvis. Renal cell carcinoma accounts for approximately 90% of all kidney cancers. Urothelial cell carcinoma is a type of cancer that occurs in the urinary system, specifically the kidney, urinary bladder, ureter, urethra and urachus. The following are types of kidney cancers:
Bellini duct carcinoma
Clear-cell sarcoma of the kidney
Mesoblastic nephroma
Wilms' tumor
Mixed epithelial stromal tumor
Squamous cell carcinoma
Juxtaglomerular cell tumor (reninoma)
Angiomyolipoma
