What is kidney cancer?
Kidney cancer occurs when a malignant tumor forms in the tissue of the kidney. The kidneys are a pair of bean-shaped organs located on either side of the spine, protected by the lower ribcage. Their main function is to filter blood and remove excess water, salt and waste from the body. Although the body has two kidneys, only part of one kidney is necessary to function.

According to the American Cancer Society, over 58,000 people were diagnosed with kidney cancer in 2010. The risk of developing kidney cancer is 1 in 67 people, with men having a higher risk than women.
