Cáncer colorrectal
Terapia hormonal sustitutiva y cáncer colorrectal
Si bien el uso de terapia hormonal sustitutiva (THS) con estrógeno y progestina en mujeres posmenopáusicas se ha asociado a distintos riesgos para la salud, un nuevo estudio publicado en "The New England Journal of Medicine" ha observado que este tratamiento disminuye significativamente el riesgo de desarrollar cáncer colorrectal.
Sus autores son del University of California, Los Angeles Medical Center (Estados Unidos), quienes recuerdan que en el año 2002 se informó que la THS aumentaba en un 26% el riesgo de cáncer de mama entre sus usuarias. No obstante, el nuevo estudio concluye que, a corto plazo, el uso de estrógeno más progestina, se asocia con una incidencia reducida del cáncer colorrectal. Pese a ello, los autores apuntan que los riesgos y beneficios de la THS deberían ser evaluados individualmente antes de iniciar este tratamiento.
