Cancer is a disease in which cells in the body grow out of control. When cancer starts in the kidney, it is called kidney and renal pelvis cancer. It can also be called renal cell cancer as that is the most common type of kidney and renal pelvis cancer.
To lower your risk of kidney and renal pelvis cancers, keep a healthy weight. Don’t smoke, or quit if you do. Be very careful if you work with the chemical trichloroethylene.
What Are the Kidneys?
The body has two kidneys, one on each side of the body, located behind the liver and stomach. The kidneys make urine, which is how the body washes liquid waste out of the body. The kidneys also play a role in controlling blood pressure and stimulating the bone marrow to make red blood cells.
What Is the Renal Pelvis?
The renal pelvis is in the center of the kidney and is responsible for collecting the urine and feeding it into the ureters, two tubes that connect the kidneys with the bladder. The bladder holds urine until it is peed out.
What Are the Symptoms of Kidney and Renal Pelvis Cancers?

What Causes Kidney and Renal Pelvis Cancers?

- Having high blood pressure. It is not known whether the increased risk is due to high blood pressure itself or the medicines used to treat it.
- Taking certain pain medicines for a long time.
- Having certain genetic conditions.
- Having a long-lasting infection with Hepatitis C.
