Signs and symptoms
The following are the most common symptoms of Wilms tumor; however, each child may experience symptoms differently. Symptoms may include:
- A nontender mass, or lump, felt or seen in the abdomen.
- Swelling of the abdomen.
- Veins that appear distended or large across the abdomen.
- Blood in the urine (hematuria).
- Pain in the abdomen from pressure on other organs near the tumor.
- Decreased appetite and weakness or tiredness.
- High blood pressure (hypertension).
If a tumor is suspected in the child’s abdomen, it is important not to apply pressure to this area. Careful bathing and handling of the child is necessary before and during any tumor evaluation. Rupture of the tumor may lead to cancer cells spreading to other tissues in the body.
These symptoms of Wilms tumor may resemble other medical conditions or serious illnesses. Always consult your child’s physician for a diagnosis.
