Wilms' Tumor Symptoms

Symptoms of Wilms' tumor vary from child to child. Because tumors often grow large before they are discovered, the main symptom is a bloated or enlarged abdomen. A mass in the abdomen also might be noticed.

Other signs of Wilms' tumor include:

• Blood in the urine
• High blood pressure
• Stomach pain
• Fever
• Nausea
• Loss of appetite
• Shortness of breath
• Constipation
• Recurring fever

If your child has these symptoms, they are probably caused by something less serious than Wilms' tumor. However, it's a good idea to talk to your child's doctor, as they may signal other health problems.
