Which factor in a patient's history would be considered a potential contraindication for hormone replacement therapy (HRT) to prevent osteoporosis?

• A. Her mother and sister have a history of breast cancer.
• B. Her 60-year-old sister has Alzheimer's disease.
• C. She is taking medication for high blood pressure.
• D. She had problems with hot flashes several years ago.

Answer: (A)

The main idea is that estrogen-containing hormone replacement therapy for osteoporosis can raise the risk of breast cancer. Because one’s mother and sister have had breast cancer, this patient already has a higher familial risk. Adding systemic estrogen through HRT could elevate her risk further, making it a potential contraindication. In such cases, clinicians typically avoid systemic HRT and instead pursue non-hormonal osteoporosis treatments (like bisphosphonates or denosumab) or other options that don’t carry the same breast cancer risk. The other factors listed don’t carry the same immediate contraindication for starting HRT: a relative with Alzheimer's disease, taking medication for high blood pressure, or a history of hot flashes years ago aren’t direct reasons to avoid HRT for osteoporosis.
