Video - Nephroblastoma (Wilms tumor)

Wilms tumor, also known as nephroblastoma, is a type of kidney cancer that occurs in children. It is common in children under the age of 5, with the majority of cases occurring in children under the age of 3. Wilms tumors tend to be encapsulated and vascularized, and do not cross the midline of the abdomen.

The common symptom of Wilms' tumor is often a painless abdominal growth. However, it may present with abdominal pain and swelling, hematuria, and can metastasize to other organs such as the lungs, the liver, and bones. Nephroblastoma is usually treated with surgery to remove the tumor and, in some cases, chemotherapy and/or radiation therapy.
