There is convincing evidence that sunlight is a leading cause of skin cancer. Skin cancer can be treated and cured without serious consequences. However, in some cases the condition can be life-threatening if not caught in time.
Skin cancer is an occupational concern for people who work under the sun.
The risk however, may be reduced through awareness of the problem, and by taking measures to prevent exposure to sunlight. Except in extreme situations, neither visible light nor infrared radiation from sunlight causes health problems. Table 1 summarizes the general features of each type. When ultraviolet radiation reaches the skin, some radiation is reflected away from the surface. The remaining radiation is scattered into the tissues just beneath the skin's surface.
