Devido à sua reduzida produção, pessoas de pele clara apresentam maiores chances de </span><span style="line-height: 15px;">desenvolver tais quadros. Objetivo: O presente estudo teve o objetivo de relacionar os efeitos da exposição solar à ocorrência de </span><span style="line-height: 15px;">lesões cancerígenas na presença de hipopigmentação cutânea. Metodologia: Realizou-se pesquisa retrospectiva em centro público </span><span style="line-height: 15px;">de tratamento ao câncer, no estado da Bahia, referente ao atendimento de indivíduos com lesões cancerígenas cutâneas (22 albinos </span><span style="line-height: 15px;">e 30 com pigmentação normal), com complementação dos dados por entrevistas a membros da Associação dos Portadores de </span><span style="line-height: 15px;">Albinismo no Estado da Bahia, com prévia obtenção do consentimento informado. Resultados: A média de idade de indivíduos </span><span style="line-height: 15px;">albinos com neoplasias foi de 34,6 anos, e 65,1 anos para indivíduos não albinos, atendidos no centro de tratamento. Entre os </span><span style="line-height: 15px;">pacientes com tumores, 42,89% dos albinos e 80% dos pacientes não albinos referiam exposição solar de forma prolongada. Nos </span><span style="line-height: 15px;">albinos com câncer de pele, verificou-se que 56% apresentaram carcinoma basocelular, o tipo de câncer de pele mais comum no </span><span style="line-height: 15px;">Brasil e com maiores chances de cura. Conclusão: A exposição ao sol sem proteção constitui um fator de risco para a ocorrência </span><span style="line-height: 15px;">de lesões cancerígenas em indivíduos albinos.</span></p> <!--[if gte
