Fibrocystic breasts refer to a common condition where breast tissue becomes lumpy or rope-like, often accompanied by tenderness or pain. This condition is caused by hormonal changes during the menstrual cycle, leading to the development of fluid-filled cysts and fibrous tissue. It is most prevalent in women of reproductive age. While fibrocystic breasts are not harmful and do not increase the risk of breast cancer, they can cause discomfort and anxiety for some women. Regular breast self-exams and clinical check-ups are recommended to monitor any changes and ensure overall breast health.
