Es lo que concluye una investigación publicada en el "Journal of the National Cancer Institute" por médicos del Brigham and Women's Hospital de Boston y de la Universidad de Harvard, que han analizados datos del Nurses' Health Study.
Los autores compararon los niveles plasmáticos de folatos y otras vitaminas del grupo B en muestras de 712 pacientes diagnosticadas de cáncer de mama y de otras 712 controles sin el tumor.
Los investigadores señalan que el ácido fólico reduce el riesgo de defectos de nacimiento, parece disminuir también el riesgo cardiovascular y ahora se observa que también disminuye las probabilidades de desarrollar un tumor mamario.
En el estudio también se observó que las vitaminas B6 y B12 parecen disminuir el riesgo de cáncer de mama en mujeres que consumen menos de 15 gramos de alcohol al día, pero no en aquellas que consumen más cantidad.
