Skin cancer is a result of damaged DNA that cannot repair itself. As a result, the damaged cells replicate at a rapid pace (more rapidly than normal skin cells), forming a tumor on the skin. Usually the tumor appears on the epidermis, or the uppermost layer of the skin, so it is visible to the human eye. That is why it is very danger for our skin. Exposure to the sun cause the Ultraviolet radiation and it's effect on our skin is terrible.
