What Is Kidney Cancer?
Kidney cancer is a disease involving the abnormal and uncontrolled growth of cells in the kidneys, a pair of organs that removes waste products from the bloodstream and excretes them as urine.
About 90 percent of kidney cancers are renal cell carcinomas, which originate in the tubules that transport waste materials from the blood to the urine.
Rarer kidney cancers include transitional cell carcinoma (originating from the lining of the renal pelvis – where urine goes before it is transported to the ureter and urinary bladder), Wilms tumor (a subtype that primarily occurs in children) and renal sarcoma (from blood vessels and connective tissues within the kidney).
