El rabdomiosarcoma es el tumor de tejidos blandos más común en los niños.

Causas, incidencia y factores de riesgo:

La causa del rabdomiosarcoma se desconoce. Es un tumor muy poco común con sólo unos varios cientos de casos nuevos al año en todos los Estados Unidos.

Algunos niños con ciertas anomalías congénitas están en mayor riesgo y algunas familias presentan una mutación genética que aumenta el riesgo. Sin embargo, la gran mayoría de los niños con rabdomiosarcoma no presentan factores de riesgo conocidos.
