Answer to Question 1

ANS: C
Early-stage growths that are localized to the epithelium and have not invaded are called cancer in situ. Cancer in situ is early-stage growth and not a tumor in differentiation but is more mature growth. Dysplastic cells do not define cancer in situ.

Answer to Question 2

ANS: C
Tumor markers include hormones, enzymes, genes, antigens, and antibodies, but not red blood cells, apoptotic cells, or neurotransmitters.
