Kidney cancer

Also called Renal cell carcinoma or Renal cancer

Kidney cancer is cancer that starts in the kidneys. It is most common in people over 60. Smoking, being overweight and high blood pressure increase the risk. It often causes no symptoms early on and is commonly found by chance during a scan for something else.

What it is

Treatment depends on the size and spread and may include surgery to remove part or all of the kidney, ablation, active monitoring of small tumours, or medicines such as targeted therapy and immunotherapy.

People can live normally with one healthy kidney.

Common signs

  • Blood in the pee
  • A lump or swelling in the side
  • Pain in the side or lower back that does not go away
  • Weight loss
  • Tiredness

How it is usually diagnosed

  • Urine and blood tests
  • Ultrasound and CT scans
  • Biopsy, sometimes

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Scan reports
  • Histology reports
  • Kidney function results
  • Urology and oncology letters

Questions to ask your doctor

  • What stage is the cancer?
  • Can part of the kidney be saved?
  • How will my remaining kidney function be checked?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Heavy blood in the pee with clots or being unable to pee: get urgent medical help
