Wilms Tumor and Other Childhood Kidney Tumors Treatment (PDQ®): Treatment - Patient Information [NCI] - General Information About Wilms Tumor and Other Childhood Kidney Tumors


Wilms tumor and other childhood kidney tumors are usually diagnosed and removed in surgery.

Once a kidney tumor is found, surgery is done to find out whether or not the tumor is cancer. If the tumor is only in the kidney, the surgeon will remove the whole kidney (nephrectomy). If there are tumors in both kidneys or if the tumor has spread outside the kidney, a piece of the tumor will be removed. In any case, a sample of tissue from the tumor is sent to a pathologist, who looks at it under a microscope to check for signs of cancer.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options depend on the following:

  • How different the tumor cells are from normal kidney cells.
  • The stage of the cancer.
  • The type and size of the tumor.
  • The age of the child.
  • Whether the tumor can be completely removed in surgery.
  • Whether the cancer has just been diagnosed or has recurred (come back).
  • Whether there are any abnormal chromosomes or genes.
  • Whether the patient is treated by pediatric experts with experience in treating patients with Wilms tumor.

Wilms tumor is rare in adults.

Wilms tumor in adults is harder to cure than in children. When a Wilms tumor is found, tests should include checking lymph nodes for cancer.
