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.What type of tissue would you guess the term carcinoma and melanoma is most closely associated with?
A)connective
B)muscle
C)epithelial
D)nervous
E)all of the above

Question

Quizplus · Accepted Answer

Carcinoma and melanoma are both types of cancers that originate in epithelial tissue, which lines the surfaces and cavities of the body. Therefore, the closest answer choice is C, epithelial. A is incorrect because connective tissue is not typically associated with these types of cancers. B and D are also incorrect because muscle tissue and nervous tissue, respectively, are different types of tissue that are not typically associated with these types of cancers. E is incorrect because it encompasses all tissue types, but only epithelial tissue is specifically associated with carcinomas and melanomas.
