Environmental Influences Appear to Contribute to Cellular Mutations That Lead

Environmental influences appear to contribute to cellular mutations that lead to tumor growth. For example, certain diets lead to higher incidence of colon cancers, and overexposure to sunlight leads to higher incidence of skin cancers. The tissues in closest contact with a carcinogen or mutagen (anything that causes genetic mutations) are obviously the ones most likely to develop tumors. Carcinomas and melanomas account for well over half of all cancers. Given this information, what type of tissue is most closely associated with the terms carcinoma and melanoma?

A) connective
B) muscle
C) epithelial
D) nervous
