Your kidneys are bean-shaped organs located on each side of your spine, just behind the intestines. Kidneys act like filters to remove excess fluid, electrolytes and waste from your blood, and retain only the essential elements. Different types of cancer can develop in the kidney.
Renal cell carcinoma is the most common type of kidney cancer in adults. It originates in the lining of tubules (very small tubes) in the kidneys and starts growing uncontrollably to form a single mass within the kidneys. More than one tumour can develop in one or both kidneys. Renal cell carcinoma occurs mainly in men aged 50 to 70 years old.
