Kidney cancer occurs when small amounts of cells in these organs begin to change and grow abnormally. The kidneys are located in the torso--one to the immediate left of the backbone, and one to the right. They filter the blood and assist the body in disposing of excess water, salt and waste products, which leave the body in the form of urine. A kidney cancer diagnosis is complicated because the organs sit deep in the body, but there are several tests that can assist the process.
