Alrededor del 8% de los pacientes con melanoma cutáneo desarrollan otro melanoma antes de los dos años del diagnóstico inicial.
Además, la proporción en aquellos pacientes con lunares atípicos es aun mayor, según un estudio publicado en "Archives of Dermatology" por investigadores de la Dartmouth Medical School (Estados Unidos).
Evaluaron la frecuencia de recidivas de melanoma y factores de riesgo en 354 pacientes. Encontraron que el 6% desarrolló un melanoma adicional al cabo de un año del diagnóstica, cifra que ascendió al 8% a los dos años. El 63% de los que desarrollaron tumores adicionales y el 37% de los que no los desarrollaron presentaban al menos un lunar atípico.
