En este estudio cruzaron los datos del Swedish Cancer Register con los del Swedish Generation Register para identificar a un grupo de más de 30.000 mujeres menores de 70 años diagnosticadas de cáncer de mama. Durante un periodo de estudio de seis años, las mujeres con cáncer de mama tuvieron dos veces mayor riesgo de cáncer de ovario que el resto de mujeres suecas (OR, 2,0; 95% IC, 1,6-2,4), mientras que en mujeres menores de 40 años con cáncer de mama era mucho mayor, más aún si se combinaba con antecedentes familiares de cáncer de mama (OR, 5,6; 95% IC, 1,8-13,1) o de cáncer de ovario (OR, 17,0; IC, 3,5-50,0).

Cáncer de mama
El cáncer de mama en una edad temprana aumenta el riesgo de cáncer de ovario
Un estudio retrospectivo realizado por investigadores del Instituto Karolinska de Estocolomo (Suecia) y recogido en la edición electrónica de “The Lancet” muestra una relación de riesgo aumentado de cáncer de ovario en mujeres que han sufrido un cáncer de mama. El mayor riesgo se da en mujeres con cáncer de mama antes de los 40 años y con antecedentes familiares de alguno o ambos tumores malignos. Como mínimo, los antecedentes familiares de cáncer de ovario suponen un riesgo del 10% de desarrollar esta patología antes de los 70 años.
