Drivers, construction workers, gardeners, window cleaners, etc. are exposed for long periods of time to the rays of the sun. This may lead to sunburn, dryness, rashes, and possibly skin cancer.
According to the American Cancer Society, one-in-five Americans will ultimately develop skin cancer, which is the most common cancer and accounts for more than 50 percent of malignancies. This means that skin cancer is as prevalent as all other forms of cancer combined. In addition, the occurrence of all types of skin cancer is on the rise.
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.
