General Information for Renal Cell Carcinoma (RCC) Patients
This fact sheet for patients reviews the cause, symptoms, tests, and prognosis for renal cell carcinoma/kidney cancer.
Renal cell cancer (also called kidney cancer or renal adenocarcinoma) is a disease in which malignant (cancer) cells are found in the lining of tubules (very small tubes) in the kidney. There are 2 kidneys, one on each side of the backbone, above the waist.
The tiny tubules in the kidneys filter and clean the blood, taking out waste products and making urine. The urine passes from each kidney into the bladder through a long tube called a ureter. The bladder stores the urine until it is passed from the body.
Cancer that starts in the ureters or the renal pelvis (the part of the kidney that collects urine and drains it to the ureters) is different from renal cell cancer.
Smoking and misuse of certain pain medicines can affect the risk of renal cell cancer.
Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for renal cell cancer include the following:
- Misusing certain pain medicines, including over-the-counter pain medicines, for a long time.
- Having certain genetic conditions, such as von Hippel-Lindau disease or hereditary papillary renal cell carcinoma.
Possible signs of renal cell cancer include blood in the urine and a lump in the abdomen.
These and other symptoms may be caused by renal cell cancer. Other conditions may cause the same symptoms. There may be no symptoms in the early stages. Symptoms may appear as the tumor grows. Check with your doctor if you have any of the following problems:
- Blood in the urine.
- A lump in the abdomen.
- A pain in the side that doesn't go away.
- Loss of appetite.
- Weight loss for no known reason.
