Los autores del trabajo, de la Universidad de Washington, muestran además que las mujeres más jóvenes, las premenopáusicas y las que reciben terapia hormonal sustitutiva tienen más probabilidades de dar falso positivo, igual que aquellas con historia familiar de cáncer de mama y las que se han sometido a biopsia previamente.
Los investigadores compararon la precisión de interpretación de mamografías de 24 radiólogos, que interpretaron un total de 8.734 mamografías realizadas a 2.169 mujeres.
La lectura varía de radiólogo a radiólogo claramente, según los resultados de este trabajo. La tasa de falsos positivos, por ejemplo, oscila entre el 2,6% y el 15,9%, algo en lo que influyen de manera importante los años de experiencia de estos profesionales. Así, en el caso de especialistas que completaron su formación hace menos de 15 años hay cuatro veces más probabilidades de que den un falso positivo que aquellos que acabaron su formación hace más de 20 años.
