    Prevention

    The best way to prevent skin cancer is to reduce your exposure to sunlight. Ultraviolet light is most intense at midday, so try to avoid sun exposure during these hours. Protect the skin by wearing hats, long-sleeved shirts, long skirts, or pants.

    Always use sunscreen:

    • Apply high-quality sunscreens with SPF (sun protection factor) ratings of at least 15.
    • Look for sunscreens that block both UVA and UVB light.
    • Apply sunscreen at least 30 minutes before going outside, and reapply it frequently.
    • Use sunscreen in winter, too.

    Examine the skin regularly for development of suspicious growths or changes in:

    • Color
    • Size
    • Texture
    • Appearance

    Also note if an existing skin sore bleeds, itches, is red and swollen (inflamed), or is painful.
