ObjectiveMalignant cutaneous melanoma is the most aggressive type of skin cancer, and its early detection and prompt initiation of treatment play an important role in reducing disease-associated morbidity and mortality. Many factors influence the diagnosis of melanoma, and its recognition is essential for the development of strategies for its early detection. This study was carried out to Identify the main variables related to the delay in diagnosis of Malignant Cutaneous Melanoma and correlate them with the time interval for making the definitive diagnosis.MethodsRetrospective analysis of 103 patient records from January 2015 to December 2020 correlating social, economic, demographic, and cultural factors with the time elapsed between the onset of symptoms and the diagnosis of malignant cutaneous melanoma.ResultsThe average time to seek medical services from the onset of symptoms was 29.54 months. The mean time for a referral from the primary to the referral service was 1.35 months, and the factors that contributed to a faster diagnosis were lesion Breslow (>1 mm), lesion growth, income range (≤1.5 minimum wages), lower phototypes (I and II), not having gone to the Basic Healthcare Units, profession (household), smoking, and type of housing.ConclusionsOur findings demonstrate that there is still a great delay in the recognition of signs and symptoms related to the diagnosis of malignant cutaneous melanoma in our country, influenced by several socioeconomic and demographic factors.
