Los investigadores, del Instituto Nacional del Cáncer de Estados Unidos, examinaron la posible asociación en 368 pacientes con melanoma y en 373 pacientes con cáncer colorrectal.
Los resultados muestran que aquellos pacientes con mayores concentraciones de arsénico en las uñas presentaron el doble de probabilidades de estar diagnosticados de melanoma que los que tenían bajas concentraciones. El riesgo no se relacionó con el color ni con el tipo de piel, ni tampoco con la historia de exposición al sol.
