Childhood tumor

The symptoms of nephroblastoma vary from person to person. Because tumors usually become larger before they are discovered, the main symptom is abdominal swelling or enlargement. Abdominal lumps may also be noticed.

Other signs of nephroblastoma include:

Blood in urine

hypertension

Stomach pain

fever

nausea

Loss of appetite

Shortness of breath

constipation

Recurrent fever

If your child has these symptoms, they may be caused by something lighter than nephroblastoma. However, talking to your child's doctor is a good idea as it may indicate other health issues.
