Get answers early for kidney cancer in children

Wilms tumor is the most common type of kidney cancer in children. It most often affects young children and can develop in one or both kidneys. With early diagnosis and treatment, many children respond well to care.

When your child needs treatment, you want a team that helps you understand what comes next. Our pediatric oncology specialists work with your family to create a personalized treatment plan and guide you through every stage of care.

What is Wilms tumor?

Wilms tumor, also called nephroblastoma, is a rare childhood cancer that starts in the kidneys. It is the most common kidney cancer in children and is most often diagnosed between ages 2 and 5.

The kidneys help remove waste from the body and make urine. When a tumor develops in a kidney, it can affect how the kidney works and may grow or spread if not treated.

Signs and Symptoms of Wilms Tumor

Children with Wilms tumor may have different symptoms. Some children have no symptoms at first, while others may experience:

  • A lump or swelling in the abdomen
  • Belly pain or discomfort
  • Blood in the urine
  • Fever
  • High blood pressure
  • Low energy levels

If you notice changes that concern you, talk with your child's clinician. Early evaluation can help identify the cause and determine the next steps.

Diagnosing Wilms Tumor

Getting a clear diagnosis is an important first step. Your child's care team may use imaging tests, lab work and other evaluations to learn more about the tumor and whether it affects one or both kidneys.

These results help your child's specialists understand the tumor and develop a treatment plan tailored to your child's needs.

Treatment for Wilms Tumor

Your child's treatment plan depends on several factors, including the size and location of the tumor and whether it has spread.

Treatment may include:

  • Surgery to remove all or part of the affected kidney
  • Chemotherapy
  • Radiation therapy
  • Ongoing monitoring and follow-up visits

Our pediatric oncology team works together to coordinate treatment and help your child receive support throughout their journey.
