C79: Secondary malignant neoplasm of other and unspecified sites
C79.0: Secondary malignant neoplasm of kidney and renal pelvis
The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.
The cancer cells have spread in your body and multiplied at another site. These are called metastases.
There are 2 kidneys in the body. There is one on each side of the spine just below the ribcage. Each kidney is made up of renal tissue and a renal pelvis. The renal tissue purifies the blood and, by doing so, produces urine. The urine gathers in the renal pelvis.
