SERMs are used for which purposes?

• A. Osteoporosis prevention and breast cancer risk reduction.
• B. To increase estrogen levels
• C. To treat hot flashes exclusively
• D. To replace estrogens in therapy

Answer: (A)

SERMs work by binding estrogen receptors and producing different effects in different tissues. In bone, they act like estrogen, helping to preserve bone density and reduce fracture risk, which is why they are used for osteoporosis prevention. In breast tissue, they block estrogen signaling, lowering the stimulus for cancer cell growth and reducing breast cancer risk in high-risk individuals. They do not raise overall estrogen levels and they are not replacements for estrogens; their benefit is in selective tissue action rather than a blanket increase of estrogen. They’re not used solely to treat hot flashes, and their role is not to replace estrogens in therapy. Together, these tissue-selective actions explain why the best answer is osteoporosis prevention and breast cancer risk reduction.
