What are the symptoms of kidney cancer?

Many people with kidney cancer do not have obvious symptoms, and about half of all kidney cancers are found by chance during a scan or test for another reason. Signs and symptoms of kidney cancer include:

  • The classic symptoms of kidney cancer are blood in the urine (haematuria), pain in your back or side, and a lump in your tummy, but only 10% of people have all three of these symptoms together
  • Back pain, night sweats, high blood pressure, and swelling of the veins around the testicle (varicocele) in men can also lead to a diagnosis of kidney cancer
  • More than 50% of renal tumours are now detected when using ultrasound for non-specific symptoms, such as general tummy pain, high blood pressure, feeling tired, weight loss, anaemia, or abnormal blood or urine tests
  • Unfortunately, 25-30% of people with kidney cancer have symptoms of cancer that has spread, such as; a persistent cough, frequent headaches, bone pain, or abnormal liver function tests.

These symptoms can be caused by many other conditions, apart from kidney cancer, so it is important to have them checked out by a doctor.
