Children with Wilms tumor may experience the following symptoms or signs. Sometimes, children with Wilms tumor do not show any of these symptoms. Or, these symptoms may be caused by a medical condition that is not a tumor.

A parent or relative may notice a large lump or feel a hard mass in the child’s belly, or notice that the belly is much larger than usual. In some cases, a rapid change to a larger diaper size alerts parents to the tumor. A few children have abdominal pain, but most of the time the tumor grows without causing pain, and the child feels and appears healthy.
Frequently, children with Wilms tumor may experience the following symptoms:
- Blood in the urine
- High blood pressure
- Anemia, which is a low level of red blood cells
- A fever that doesn’t go away
