Information that could change or save your child’s life.
We’ve gathered the most important resources on pediatric kidney disease, Wilms tumor, hemihypertrophy, and childhood kidney cancer to help families, caregivers, and providers get what they need quickly.

What Is Wilms Tumor?

Wilms tumor (nephroblastoma) is the most common type of kidney cancer in children, typically affecting children ages 3–4, though it can occur at any age. It is often found as a painless lump or swelling in the abdomen — exactly like what our family noticed with Tre.

Key Facts:

  • Approximately 500 children are diagnosed in the United States each year
  • It can affect one or both kidneys
  • With early detection and proper treatment, survival rates are high
  • Many families receive no warning before diagnosis — awareness is everything

What Is Hemihypertrophy?

Hemihypertrophy (also called hemihyperplasia) is a condition where one side of the body grows larger than the other. It may be isolated or associated with specific genetic conditions.
Children with hemihypertrophy carry a significantly elevated risk of developing Wilms tumor and other intra-abdominal tumors. Standard medical guidance recommends routine abdominal ultrasound surveillance every 3–4 months until age 7–8 for affected children.

If your child has been diagnosed with hemihypertrophy:

Ask your pediatrician or specialist about kidney surveillance protocols. Keep all surveillance appointments, even if your child appears completely healthy. Tre appeared healthy. The only sign was a subtle abdominal bulge. Surveillance saves lives.

Warning Signs to Watch For

Wilms tumor is often painless and may produce few or no symptoms in its early stages. Trust your instincts, you know your child.

  • A lump, mass, or swelling in the abdomen
  • Abdominal pain or discomfort
  • Blood in the urine
  • Fever without an obvious cause
  • Loss of appetite, nausea, or vomiting
  • High blood pressure
If you notice any of these signs, contact your child’s physician promptly. Do not wait.
