Normalmente, sólo las mujeres a las que se ha extirpado el útero reciben terapia sólo con estrógenos, dado que se sabe que la hormona incrementa el riesgo de cáncer de útero. El resto de mujeres suelen tomar la combinación de estrógeno y progestina.
La investigación ha estudiado una muestra de más de 44.000 mujeres que iniciaron la terapia cuando tenían, de media, 57 años de edad. Durante el período de estudio desarrollaron cáncer de ovario 329 mujeres.
