A Provider Considers Cancer Prophylaxis with Tamoxifen for a 45-Year-Old

A provider considers cancer prophylaxis with tamoxifen for a 45-year-old patient with a family history of breast cancer. According to her health history, she had one child at age 35 and developed deep vein thrombosis (DVT) during the pregnancy. She has not had a hysterectomy. What information from the patient's history informs the provider's decision regarding tamoxifen?

A) Because of her family risk and late childbearing, this drug is a good choice for her.
B) Her history of DVT outweighs any possible benefits she may have with this drug.
C) Since she has not had a hysterectomy, the risk of endometrial cancer is too great.
D) When she turns 50 years old, this drug will carry fewer risks for her.
