Artificial sources of UV radiation, such as sunlamps and tanning booths, can also cause skin cancer. Although anyone can get skin cancer, the risk is greatest for people who have fair skin that freckles easily – often those with red or blond hair and blue or light colored eyes. In addition, skin cancer is related to lifetime exposure to UV radiation. Most skin cancers appear after age 50, but the sun’s damaging effects begin at an early age. Therefore, protection should start in childhood to prevent skin cancer later in life.
