Answer to Question 1

ANS: D
Progesterone causes maturation of the mammary gland tissue, specifically acinar structures of the lobules. Estrogen increases the vascularity of the breast tissue. Testosterone has no bearing on breast development. Prolactin is produced after birth and released from the pituitary gland. It is produced in response to infant suckling and emptying of the breasts.

Answer to Question 2

ANS: A
The physiologic alterations in breast size and activity reach their minimal level about 5 to 7 days after menstruation stops. All women should perform BSE during this phase of the menstrual cycle.
