Get StartedSymptoms
By Mayo Clinic staffWilms' tumor may also go undetected early on, because the tumors can grow large without causing pain. However, even when they're large, most of these tumors are found before they have a chance to spread (metastasize) to other parts of the body. Your child may appear healthy or may have:
- Abdominal swelling
- An abdominal mass you can feel
- Fever
- Blood in the urine
- Reduced appetite
- High blood pressure
- Constipation
- Stomach pain
- Nausea
When to see a doctor
Take your child to the doctor if you detect an abdominal mass or if you notice blood in the urine. There may be other signs and symptoms, such as fever, high blood pressure, constipation, reduced appetite, abdominal pain and weight loss. These symptoms are much more likely to be caused by something other than Wilms' tumor, but see your child's doctor to evaluate them.
If your child has been treated for Wilms' tumor, report any new signs or symptoms to your child's doctor. These problems may be a sign of cancer returning or of side effects of treatment.
