Which statement best describes the natural history of fibrocystic breast changes?

• A. Most spontaneously resolve on their own and fluctuate with menstrual hormones.
• B. Persist without change
• C. Progress to invasive cancer
• D. Require lumpectomy

Answer: (A)

Fibrocystic breast changes are benign and driven by hormonal cycling. The breast tissue often becomes nodular with cysts and fibrosis, causing lumps and tenderness that vary with the menstrual cycle, usually worsening in the luteal/premenstrual phase and improving after menses. Because these changes are hormone-responsive and noncancerous, they typically wax and wane and often resolve on their own over time, especially after menopause. They do not progress to invasive cancer, and a lumpectomy is not needed unless there is a suspicious lesion that requires evaluation. This dynamic, cyclical, and self-limited pattern is why the statement about spontaneous resolution and fluctuation with menstrual hormones best describes their natural history.
