For people with actinic keratosis, cumulative skin damage is caused by repeated exposure to all ultraviolet light, including that found in sunshine. Over the years, the genetic material of cells may become irreparably damaged and produce these pre-cancerous lesions. The lesions, like those seen here on the arm, may later become the more invasive cancer, squamous cell carcinoma.
