Why is fair skin more prone to skin cancer?

What is the relationship between skin color and skin cancer?

Skin cancer is less common in persons with skin of color than in light-skinned Caucasians but is often associated with greater morbidity and mortality. Thus, it is crucial that physicians become familiar with skin cancer in persons of color so as to maximize the likelihood of early detection of these tumors.

Why is a light skinned person more susceptible to malignant melanoma?

Is melanoma more common in light skinned people?

Why is it less likely that melanomas result from UV light?

UVB exposure damages DNA directly, while UVA is thought to inflict its damage indirectly by inducing melanin free radicals that react with DNA to form oxidative damage that leads to melanoma.
