Skin cancer is the most prevalent of all types of cancers. It is estimated that more than one million Americans develop skin cancer every year. Fair-skinned people who sunburn easily are at a particularly high risk for developing skin cancer. Other less important factors include repeated medical and industrial x-ray exposure, scarring from diseases or burns, occupational exposure to compounds such as coal tar and arsenic, and family history.
