Your Friend Is Concerned Because Although She Has Never Been

Your friend is concerned because although she has never been pregnant, her breasts are producing milk. When she went to the doctor, he sent her to the MRI lab for a brain scan. She was too embarrassed to ask the doctor why. What do you tell her?

A) "They were actually scanning your thyroid gland, not your brain. Are you getting enough iodine in your diet?"
B) "LH and FSH from the posterior pituitary stimulate milk production. The doctor wants to rule out excess levels of estrogen in the pituitary stalk."
C) "The MRI technician must have mixed up your patient records. He should have done a thoracic scan instead."
D) "Prolactin from the anterior pituitary stimulates milk production. The doctor probably wants to rule out a pituitary tumor."
