- Wilms' tumor, which is a type of kidney cancer that usually develops in children under the age of 5
Estimated new cases and deaths from kidney (renal cell and renal pelvis) cancer in the United States each year:
- New cases: 51,190
- Deaths: 12,890
Common symptoms of kidney cancer include:
- Blood in the urine (making the urine slightly rusty to deep red)
- Pain in the side that does not go away

Surgery is the most common treatment for kidney cancer. The operation to remove a kidney is called a nephrectomy. There are several types of nephrectomies, depending mainly on the stage of the tumor.
