Los estudios sobre el efecto del selenio sobre este tipo de cáncer han ofrecido resultados contrapuestos, aunque en su mayoría se llevaron a cabo con pocos pacientes.
Los autores han examinado datos de tres ensayos clínicos con pacientes que ya habían sido operados de cáncer colorrectal. Tras ajustar diversos factores, se comprobó que la tasa de recurrencia de este tipo de tumor era más baja entre aquellos pacientes que presentaban en sangre elevadas concentraciones del mineral. Concretamente, el riesgo es un 44% entre los que tenían los niveles más altos respecto a aquellos que tenían los más bajos.
