What is the role of estrogen in breast cancer progression?

• A. Estrogen can inhibit the growth of breast cancer cells
• B. Estrogen can promote the growth of certain types of breast cancer cells
• C. Estrogen has no effect on breast cancer
• D. Estrogen is used solely for treatment of breast cancer

Answer: (B)

Estrogen plays a significant role in the progression of certain types of breast cancer, particularly hormone receptor-positive breast cancers. Many breast cancers depend on estrogen to grow and proliferate. The presence of estrogen can bind to estrogen receptors on cancer cells, activating signaling pathways that promote cell division and tumor growth. This mechanism is why tumors that express these hormone receptors are often referred to as estrogen receptor-positive (ER+). Understanding the role of estrogen in breast cancer is crucial for treatment strategies. Therapies often target these estrogen receptors to impede the action of estrogen on cancer cells. Medications such as selective estrogen receptor modulators (SERMs) and aromatase inhibitors are commonly used in the management of breast cancer to inhibit estrogen’s effects. This understanding of estrogen’s role helps in developing personalized treatment plans. Using hormone receptor status to guide therapy is an essential component of modern breast cancer management, highlighting the importance of monitoring estrogen levels and receptor expression in affected individuals.
