Tumor de Wilms - Overview

Nombres alternativos

Tumor del riñón o Tumor renal; Nefroblastoma

Definición:

Es un tipo de cáncer renal que se presenta en los niños.

Causas, incidencia y factores de riesgo:

El tumor de Wilms es la forma más común de cáncer del riñón en la infancia y su causa exacta en la mayoría de los niños se desconoce.

La ausencia del iris (aniridia) es un defecto congénito que algunas veces está asociado con el tumor de Wilms. Otros defectos congénitos ligados a este tipo de cáncer renal abarcan algunos problemas de las vías urinarias y el agrandamiento de un lado del cuerpo, una afección llamada hemihipertrofia.

Es más común entre algunos hermanos y gemelos, lo cual sugiere una posible causa genética.

La enfermedad ocurre en aproximadamente 1 de cada 200.000 a 250.000 niños. Por lo general ataca cuando el niño tiene más o menos tres años y rara vez se presenta después de los 8 años.
