espanolLa relacion entre la vitamina D y diversos tumores ha sido objeto de estudio por varios autores en los ultimos anos. El papel protector de la vitamina D se ha confirmado en estudios epidemiologicos para tumores como el de colon y se ha sugerido en el melanoma. La vitamina D podria tener un papel antitumoral, de tal manera que una menor actividad de la vitamina D estaria relacionada con un mayor riesgo de melanoma. La mayor parte de la vitamina D se obtiene a traves de la radiacion ultravioleta. Surge asi la controversia entre el beneficio de la vitamina D y su funcion antitumoral, frente a la radiacion ultravioleta, carcinogeno conocido que altera el ADN de las celulas y aumenta el riesgo de cancer cutaneo. El objetivo de nuestra revision es proporcionar un analisis detallado que hace referencia al actual interes en la vitamina D y el melanoma.
