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. If you are concerned about a symptom or sign on this list, please talk with your child’s doctor.
Usually, Wilms tumor is found before it spreads to other parts of the body. 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 for most, 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 (low levels of red blood cells)
- A fever that doesn’t go away
Your child’s doctor will ask you questions about the symptoms your child is experiencing to help find out the cause of the problem, called a diagnosis. This may include how long your child has been experiencing the symptom(s) and how often.
If cancer is diagnosed, relieving symptoms and side effects remains an important part of your child’s cancer care and treatment. This may also be called symptom management, palliative care, or supportive care. Be sure to talk with your child’s health care team about symptoms your child experiences, including any new symptoms or a change in symptoms.
