Fibrocystic changes refer to a common condition in which the breast tissue becomes lumpy or rope-like, often accompanied by tenderness or discomfort. These changes are typically caused by hormonal fluctuations, particularly during the menstrual cycle, and are most prevalent in women of reproductive age. While fibrocystic changes are not considered a disease, they can lead to the formation of fluid-filled cysts in the breast. This condition is generally benign and does not increase the risk of breast cancer. Regular breast self-exams and clinical evaluations can help monitor any changes in breast tissue.
