Signs and Symptoms

The signs and symptoms of kidney cancer can be quite subtle.  The most overt symptom is blood in the pee.  The UK has undertaken an excellent public awareness campaign to emphasize that blood in the urine is a symptoms which needs immediate follow-up and should be taken seriously by the patient and the general practitioner.

Early kidney cancers do not usually cause any signs or symptoms, but larger ones might. Some possible signs and symptoms of kidney cancer include:

  • Blood in the urine (hematuria)
  • Low back pain on one side (not caused by injury)
  • A mass (lump) on the side or lower back
  • Fatigue (tiredness)
  • Loss of appetite
  • Weight loss not caused by dieting
  • Fever that is not caused by an infection and that doesn’t go away
  • Anemia (low red blood cell counts)

These signs and symptoms can be caused by kidney cancer (or another type of cancer), but more often they are caused by other, benign, diseases. For example, blood in the urine is most often caused by a bladder or urinary tract infection or a kidney stone. Still, if you have any of these symptoms, see a doctor so that the cause can be found and treated, if needed.
