A nurse is teaching a client about fibrocystic breasts. Which of the following statements should the nurse include in the teaching?

Brief Introduction: Fibrocystic breast changes involve the development of fluid-filled cysts and fibrous tissue, often presenting as lumpy or rope-like textures in the breast parenchyma. These changes are typically bilateral and fluctuate in size and tenderness in synchronization with the luteal phase of the menstrual cycle. Rationale: A. Fibrocystic breast changes are exceptionally common, affecting approximately 50% of women at some point during their reproductive years. Labeling the condition as rare is factually incorrect and may cause unnecessary alarm when a client feels a benign lump that is statistically likely to be fibrocystic. B. Symptoms typically resolve or significantly improve after menopause due to the natural decline in ovarian follicular activity. Because the condition is driven by cyclic hormones, the cessation of the menstrual cycle leads to a reduction in breast engorgement and the flattening of existing cysts. C. Clinical evidence confirms that simple fibrocystic changes are benign and do not increase the statistical risk of developing mammary adenocarcinoma. They can make mammographic interpretation more complex, but they do not involve the cellular atypia required to be classified as a precancerous state. D. The primary etiology of fibrocystic changes is the cumulative effect of estrogen and progesterone on breast tissue. These hormones cause the milk glands and ducts to enlarge and retain fluid, leading to the characteristic swelling and discomfort that occurs just before menstruation begins.
