Key Statistics for Wilms Tumors
Wilms tumor is the most common type of kidney cancer in children. Each year, about 500 to 600 new cases of Wilms tumor are diagnosed in the United States. This number has been fairly stable for many years. About 5% of all cancers in children are Wilms tumors.
Wilms tumors tend to occur in young children. The average age of children when they are diagnosed is about 3 to 4 years. These tumors become less common as children grow older. They're very rare in adults, although cases have been reported.
Wilms tumors are slightly more common in girls than in boys. The risk of Wilms tumor is slightly higher in Black children than in White children and is lowest among Asian American children.
