<unk> -cell cancer is a very common skin cancer. It is much more common in fair-skinned individuals with a family history of<unk> -cell cancer and increases in incidence closer to the equator or at higher altitude. There are approximately 800,000 new cases yearly in the United States alone. Up to 30% of White people develop<unk> s in their lifetime. In Canada, the most common skin cancer is<unk>  (as much as one third of all cancer diagnoses), affecting 1 in 7 individuals over a lifetime. In the United States approximately 3 out of 10 White people develop a<unk>  during their lifetime. This tumor accounts for approximately 70% of non-melanoma skin cancers. In 80 percent of all cases,<unk>  affects the skin of head and neck. Furthermore, there appears to be an increase in the incidence of<unk> -cell cancer of the trunk in recent years. Most sporadic<unk>  arises in small numbers on sun-exposed skin of people over age 50, although younger people may also be affected. The development of multiple<unk> -cell cancer at an early age could be indicative of nevoid<unk>  syndrome, also known as Gorlin Syndrome.
