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.
