Wilms' tumor doesn't always cause signs and symptoms. Children with Wilms' tumor may appear healthy, or they may experience:
- Abdominal swelling
- An abdominal mass you can feel
- Abdominal pain
- Blood in the urine
When to see a doctor
Make an appointment with your child's doctor if you notice any signs or symptoms that worry you. The signs and symptoms associated with Wilms' tumor aren't specific to the condition and are much more likely to be caused by something else.
