Ultraviolet radiation is believed to contribute to the development of<unk>  by inducing mutations in epidermal keratinocytes, leading to proliferation of atypical cells. Therefore, preventive measures for<unk> s are targeted at limiting exposure to solar radiation, including: * Limiting extent of sun exposure * Avoid sun exposure during noontime hours between 10:00 AM and 2:00 PM when UV light is most powerful * Minimize all time in the sun, since UV exposure occurs even in the winter and on cloudy days * Using sun protection * Applying sunscreens with SPF ratings 30 or greater that also block both UVA and UVB light, at least every 2 hours and after swimming or sweating * Applying sunscreen at least 15 minutes before going outside, as this allows time for the sunscreen to be absorbed appropriately by the skin * Wearing sun protective clothing such as hats, sunglasses, long-sleeved shirts, long skirts, or trousers Recent research implicating human papillomavirus (HPV) in the development of<unk> s suggests that HPV prevention might in turn help prevent development of<unk> s, as UV-induced mutations and oncogenic transformation are likely facilitated in cases of active HPV infection. A key component of HPV prevention includes vaccination, and the CDC currently recommends routine vaccination in all children at age 11 or 12. There is some data that in individuals with a history of non-melanoma skin cancer, a low-fat diet can serve as a preventative measure against future<unk> .
