Lifetime ultraviolet radiation exposure and lentigo maligna melanoma

Although ultraviolet light is considered a key factor in the etiology of malignant melanoma (MM), the relationship between sunlight and MM is complex. Intermittent exposure and sunburns are far more predictive of melanoma than chronic exposure, and melanoma can arise in non-sun exposed sites. Furthermore, retrospective studies have shown that outdoor workers exposed to sunlight chronically are not at higher risk of melanoma compared with indoor workers living at the same latitude.
