__**Causes of Skin Cancer**__ Spending a lot of time in a strong sunlight may cause some kind of skin cancer. Sun radiation is life-sustaining, but the higher-energy part of the sunlight spectrum brings the danger of skin cancer. When living tissue is irradiated, its molecular structure is disrupted, thus initiating a chain of reactions, many of which are not the usual ones associated with the living of ganism. Ultraviolet radiation from the sun is the main cause of skin cancer. Energy from the sun actually is a form of radiation. It consists of visible light and other rays that people can't see. Invisible radiation, for instance, makes sunlight feel hot. Ultraviolet also is invisible, and causes sunburn and sun tan. Ultraviolet rays damages DNA, which is the genetic material that makes up genes. Genes control the growth and overall health of skin cells. If the genetic damage is severe, a normal skin cell may begin to grow in the uncontrolled, disorderly way of cancer cells.
