Wilms' Tumor Screening and Prevention

Wilms' Tumor Screening

Cancer screening exams are important medical tests done when you're at risk but don't have symptoms. They help find cancer at its earliest stage, when the chances for successful treatment are highest.

Wilms' tumors are rare, and there are no tests that have proven efficient and effective for the general public.

However, if your baby or infant has a certain syndrome or birth defect that raises the risk for Wilms' tumor, you should speak to your child's doctor. Your child may need frequent examinations and ultrasounds until they are older.

Very rarely, Wilms' tumor runs in families. Tell your doctor if anyone else in your family has had a Wilms' tumor. If so, frequent examinations and ultrasounds may be needed.

Wilms' Tumor Risk Factors

Anything that increases your child's chance of getting Wilms' tumor is a risk factor. Although we don't know exactly what causes Wilms' tumors, some things may make your child more likely to develop the disease.

Risk factors include:

  • Age: Most children who develop Wilms' tumors are between 3 and 5 years old
  • Race: Wilms' tumor is more common in African American children. It is least prevalent in Asian American children
  • Gender: It is more common in females
  • Birth defect syndromes, including:
    • WAGR
    • Beckwith-Wiedemann
    • Denys-Drash
  • Other birth defects, including:
    • Aniridia (complete or partial lack of the iris [colored area] of the eyes)
    • Hemihypertrophy (an oversized arm and/or leg on one side of the body)
    • Cryptorchidism (failure of the testicles to descend into the scrotum) in boys
    • Hypospadias (defect in boys where the urinary opening is on the underside of the penis)
  • Other genetic conditions, including:
    • Perlman syndrome
    • Sotos syndrome
    • Simpson-Golabi-Behmel syndrome
