Definition
By Mayo Clinic staffKidney cancer is cancer that originates in the kidneys. Your kidneys are two bean-shaped organs, each about the size of your fist. They're located behind your abdominal organs, with one kidney on each side of your spine.
In adults, the most common type of kidney cancer is renal cell carcinoma. Other less common types of kidney cancer can occur. Young children are more likely to develop a kind of kidney cancer called Wilms' tumor.
The incidence of kidney cancer seems to be increasing. One reason for this may be the fact that imaging techniques such as computerized tomography (CT) are being used more often. These tests may lead to the accidental discovery of more kidney cancers.
