Abstract: Skin cancers are most common cancers in human populations, with more than 550,000 new cases annually in the United States, representing at least 30% of annual primary cancer diagnosed. It has been well recognized that solar ultraviolet radiation is the predominant causal factor in cutaneous carcinogenesis in humans. The risk degree of solar ultraviolet radiation in terms of inducing skin cancers in humans varies among the population. Some of factors, such as an individual's skin type, are beyond one's control. But many of others are manageable. Among them are outdoor activity patterns and all factors related including spectrum of the ultraviolet radiation, intensity of the ultraviolet radiation and total exposure time. This paper will discuss the factors affecting the risk degree of solar ultraviolet radiation-induced skin cancers in humans and present a novel method and sensing device in order to help in preventing such cancers in humans.!
