Kidney (renal) tumours

Kidney (or renal) tumours affect cells in the kidneys.

Wilms tumour (also known as nephroblastoma) is the most common type of kidney tumour in children. They are more common in younger children, usually three to four-year-olds, than older children.

Other types of kidney tumours in children include:

  • clear cell sarcoma of the kidney
  • malignant rhabdoid tumour of the kidney
  • mesoblastic nephroma
  • renal cell carcinoma.

These types of kidney tumours are more common in teenagers and young adults than in young children.
