The kidneys are the two organs responsible for filtering toxic substances from the blood and eliminating them in the urine. In these organs, tumours may appear on the tissue itself or in the urinary tract. Tumours or lumps originate in cells that line small tubes in the renal cortex called renal tubules. They may be benign or malignant.
Kidney cancer can be classified into different types based on the tumour cell properties. The most frequent cell type is the so-called "clear cell" and represents around 75% of cases, followed by the papillary type in 15% and the chromophobe type in around 5%. There are other cell subtypes, but at a much lower percentage.
However, kidney tumours can also be benign, with the most frequent being angiomyolipomas and oncocytomas.

How many people does kidney cancer affect?
This tumour is more frequent in men than in women (1.5:1) and appears more frequently after 60 or 70 years. Kidney cancer accounts for 2-3% of all cancers and represents 90% of solid tumours originating in the kidney.
