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
- Loss of appetite
- Shortness of breath
- 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.
