Symptoms of kidney cancer

Kidney cancer may not cause any signs or symptoms in its early stages. It is usually found on an ultrasound or x-ray done for another reason. Signs and symptoms often appear as the tumour grows into surrounding tissues and organs. Other health conditions can cause the same symptoms as kidney cancer.

See your doctor if you have these signs or symptoms:

• blood in the urine (pee) (called hematuria) (most common)
• pain in the back and side of the abdomen
• a lump that can be felt in the abdomen
• swelling of the legs and ankles
• high blood pressure
• low red blood cell count (called anemia)
• fatigue
• night sweats
• weight loss
• loss of appetite
• fever
• for men, a large swollen vein in the scrotum (called a varicocele)
