DiYES International School – Wilms Tumor in children is a rare but serious form of kidney cancer that primarily affects children under the age of 5. It is one of the most common types of kidney cancer in children and typically arises in one kidney, though in rare cases, it can affect both. Early detection and treatment are crucial for improving the chances of successful treatment and long-term survival. This article explores the symptoms, diagnosis, and treatment options for Wilms Tumor, providing essential information for parents, caregivers, and healthcare professionals.
Symptoms of Wilms Tumor
Wilms Tumor often develops without early symptoms, making early detection difficult. As the tumor grows, signs may appear.
The most common symptom is an abdominal mass. Parents usually notice it while bathing or dressing the child. The mass is often painless and may be large enough to feel. Children may also experience abdominal pain or swelling. The tumor’s size can cause a visible bulge in the abdomen.
Other symptoms of Wilms Tumor can include:
- Blood in the urine (hematuria): This occurs when the tumor causes damage to blood vessels in the kidney.
- Fever: Some children with Wilms Tumor may develop a low-grade fever, though this is less common.
- High blood pressure (hypertension): This can occur if the tumor disrupts normal kidney function or produces substances that affect blood pressure.
- Loss of appetite and weight loss: As the tumor grows, it may cause the child to feel unwell, leading to a decrease in appetite and weight loss.
- Nausea and vomiting: If the tumor causes a blockage in the kidney or affects nearby organs, it may lead to gastrointestinal symptoms like nausea or vomiting.
If any of these symptoms are observed, it is important for parents to seek medical attention immediately for a thorough evaluation and diagnosis.

Diagnosis of Wilms Tumor
When Wilms Tumor is suspected, the first step in diagnosis is a physical examination, where the doctor may palpate the abdomen to feel for a mass. If a mass is detected, further diagnostic tests are necessary to confirm the presence of a tumor and to determine its size, location, and potential spread.
The primary diagnostic tools used to detect Wilms Tumor include:
- Ultrasound: An abdominal ultrasound is usually the first imaging test performed when a mass is suspected. It helps identify the size and characteristics of the tumor and assess its effect on the kidney.
- CT Scan (Computed Tomography) or MRI (Magnetic Resonance Imaging): These imaging techniques provide more detailed views of the tumor and help doctors determine whether it has spread to other parts of the body. They are particularly useful for evaluating the lymph nodes and lungs.
- Blood and Urine Tests: Blood tests can provide information about kidney function and the presence of any abnormalities. Urine tests are used to detect blood or other signs of kidney damage.
- Biopsy: In some cases, a biopsy may be performed to confirm the diagnosis. However, a biopsy is not always necessary, as Wilms Tumor is usually diagnosed based on imaging results.
Once a diagnosis of Wilms Tumor is confirmed, doctors will determine the stage of the cancer, which refers to how far the tumor has spread. This helps guide treatment decisions and predict the child’s prognosis.

Treatment Options for Wilms Tumor
Treatment for Wilms Tumor usually involves a combination of surgery, chemotherapy, and sometimes radiation therapy. The specific treatment plan depends on the size and stage of the tumor, as well as the child’s overall health. Early detection and intervention play a critical role in successful treatment outcomes.
Surgery
The primary treatment for Wilms Tumor is surgery, which removes the tumor and often the affected kidney. In some cases, if the tumor is small and has not spread, doctors may remove only the tumor, preserving the kidney. However, in most cases, surgeons remove the entire affected kidney in a procedure called a nephrectomy.
Doctors typically perform surgery as the first step in treating Wilms Tumor to remove the bulk of the tumor. After surgery, the child may need additional treatments, such as chemotherapy or radiation, to destroy any remaining cancer cells.
Chemotherapy
Doctors commonly use chemotherapy after surgery to treat any remaining cancer cells. Chemotherapy also targets cancer cells if the tumor has spread to other parts of the body. Doctors administer chemotherapy drugs intravenously, and these drugs work by targeting and killing rapidly dividing cancer cells.
The specific chemotherapy regimen depends on the stage and type of Wilms Tumor. In most cases, doctors administer chemotherapy over several months. Side effects, such as nausea, fatigue, and hair loss, often occur but remain manageable.
Radiation Therapy
Doctors may recommend radiation therapy in some cases, especially if the tumor is large, has spread, or was not fully removed during surgery. Radiation therapy uses high-energy beams to target and destroy cancer cells in specific areas of the body.
Doctors typically reserve radiation for cases where surgery cannot fully remove the tumor or if the cancer has spread to nearby lymph nodes or other organs.
Follow-Up Care
After the initial treatment, children with Wilms Tumor require ongoing follow-up care to monitor for any recurrence of the cancer. Regular check-ups, imaging tests, and blood work are part of the long-term care plan. These visits are essential to ensure that the child remains cancer-free and to address any late effects of treatment.
