What is Fibrocystic Breast Disease
Fibrocystic breast disease is a general term that refers to any common, benign (non-cancerous) breast change, including breast pain, cysts, and non-cancerous lumps in the breast. Fibrocystic breast disease is not a disease by definition, but a condition with symptoms. Many doctors refer to it as fibrocystic breast changes instead.
Approximately 30% of all women have this condition. It occurs most frequently in women of childbearing age, especially between 30 and 50 years of age, and rarely develops in postmenopausal women, unless they are on estrogen replacement therapy.
