b. Antiestrogen drugs increase the risk for endometrial cancer.
c. Aromatase inhibitors block the production of estrogen by the ovaries.

ANS: B
Antiestrogen drugs cause proliferation of endometrial tissue by acting as receptor agonists at receptors in the uterus. Antiestrogen drugs increase the risk of thromboembolic events. Aromatase inhibitors block the production of estrogen from androgenic precursors, not by the ovaries. Aromatase inhibitors are used to treat ER-positive breast cancer.
