Una o dos consumiciones de alcohol diarias parecen disminuir moderadamente el riesgo de desarrollar cáncer de riñón, según concluye un estudio publicado en el "Journal of the National Cancer Institute" por investigadores del Brigham and Women's Hospital de Boston.
Aunque otros estudios han asociado el consumo moderado de alcohol a un menor riesgo de este tipo de cáncer, los resultados no han sido concluyentes, en especial referidos a distintos tipos de bebida, mientras que el presente estudio indica que la reducción del riesgo es independientemente del tipo de bebida consumida.
Los autores examinaron datos de más de 530.000 mujeres y más de 229.000 varones, con un seguimiento de entre 7 a 20 años. Desarrollaron cáncer renal 711 mujeres y 719 varones. Los resultados indican que la incidencia fue de 23 casos por cada 100.000 no bebedores/año y a 15 casos por cada 100.000 bebedores moderados/año, lo que significa que el consumo moderado disminuye en un 25% el riesgo de cáncer de riñón respecto a los abstemios.
