Renal cell cancer is a disease in which malignant (cancer) cells form in tubules of the kidney. Smoking and misuse of certain pain medicines can affect the risk of renal cell cancer. Signs of renal cell cancer include blood in the urine and a lump in the abdomen.
Tests that examine the abdomen and kidneys are used to detect and diagnose renal cell cancer.
Certain factors affect prognosis (chance of recovery) and treatment options.
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. This is called transitional cell cancer of the renal pelvis and ureter. These and other signs and symptoms may be caused by renal cell cancer or by other conditions. There may be no signs or symptoms in the early stages. Signs and symptoms may appear as the tumor grows:
- 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.
