There is no evidence to support or refute adult population screening for malignant<unk> . Ultraviolet radiation Minimizing exposure to sources of ultraviolet radiation (the sun and sunbeds), following sun protection measures and wearing sun protective clothing (long-sleeved shirts, long trousers, and broad-brimmed hats) can offer protection. Using artificial light for tanning was once believed to help prevent skin cancers, but it can actually lead to an increased incidence of<unk> s. UV nail lamps, which are used in nail salons to dry nail polish, are another common and widespread source of UV radiation that could be avoided. Although the risk of developing skin cancer through UV nail lamp use is low, it is still recommended to wear fingerless gloves and/or apply SPF 30 or greater sunscreen to the hands before using a UV nail lamp. The body uses UV light to generate vitamin D so there is a need to balance getting enough sunlight to maintain healthy vitamin D levels and reducing the risk of<unk> ; it takes around a half-hour of sunlight for the body to generate its vitamin D for the day and this is about the same amount of time it takes for fair-skinned people to get a sunburn. Exposure to sunlight can be intermittent instead of all at one time. Sunscreen Sunscreen appears to be effective in preventing<unk> . In the past, use of sunscreens with a sun protection factor (SPF) rating of 50 or higher on exposed areas were recommended; as older sunscreens more effectively blocked UVA with higher SPF. Currently, newer sunscreen ingredients (avobenzone, zinc oxide, and titanium dioxide) effectively block both UVA and UVB even at lower SPFs. Sunscreen also protects against squamous cell carcinoma, another skin cancer. Concerns have been raised that sunscreen might create a false sense of security against sun damage. Medications A 2005 review found tentative evidence that statin and fibrate medication may decrease the risk of<unk> . A 2006 review however did not support any benefit.
