What factor is highlighted as affecting breast tissue during ultrasound evaluation?

• A. Hormones
• B. Diet
• C. Exercise
• D. Temperature

Answer: (A)

Breast tissue on ultrasound changes with hormonal status. Estrogen and progesterone drive the growth and secretory changes in glandular and fibrous tissue, so the echotexture and density of the breast parenchyma vary across the menstrual cycle, during pregnancy or lactation, and with hormone therapy. This hormonal modulation can alter how tissues and any lesions appear on ultrasound, which is why hormones are highlighted as the influencing factor. Diet, exercise, and temperature don’t produce the same consistent, cycle-related changes in breast tissue seen on ultrasound.
