Signs and Symptoms
Kidney cancer rarely causes signs or symptoms in its early stages. In the later stages, the most common sign of both renal cell and transitional cell cancers is blood in the urine (hematuria). You may notice the blood when you urinate, or your doctor may detect it by urinalysis, a test that specifically checks the contents of your urine. Other possible signs and symptoms may include:
- A pain in the back just below the ribs that doesn’t go away
- A mass in the area of the kidneys that’s discovered during an examination
- Weight loss
- Fatigue
- Intermittent fever
- Pain in other parts of the body if the cancer has metastasized
