Ultraviolet light or UV rays from the sun as well as from sunlamps and tanning booths is the primary cause of cancer. It doesn’t matter what your race is, skin type, age, what part of the world you live in, you can still get skin cancer. You are at greater risk if you are fair and freckle easily, have light eyes and hair, have a large number of moles or they may be unusual sizes and shapes, you have a family history of sunburns that blistered, you live close to the equator or at higher altitude or live in areas where there is sunshine year-round.
