Which hormone therapy is sometimes used in the treatment of breast cancer?

• A. Estrogen therapy
• B. Progestin therapy
• C. Aromatase inhibitors
• D. Beta-blockers

Answer: (C)

Aromatase inhibitors play a significant role in the treatment of hormone receptor-positive breast cancers, particularly in postmenopausal women. These medications work by inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogen in the body. By reducing estrogen levels, aromatase inhibitors help slow or stop the growth of tumors that depend on estrogen for their development and proliferation.

This mechanism is particularly important because certain breast cancers are driven by estrogen, and lowering its availability can be an effective strategy in managing the disease. Aromatase inhibitors are typically used as adjuvant therapy after initial treatment or as a primary therapy in advanced breast cancer. Their effectiveness makes them a critical component of breast cancer treatment protocols that target hormone-sensitive cancers.
