Fibrocystic breast disease.

Fibrocystic breast disease is characterized by breast pain, lumpiness or cysts. The few patients who have atypia on breast biopsy are at substantially increased risk for the development of breast cancer. Management of fibrocystic breast disease involves monitoring for breast cancer by repeated physical and mammographic examinations. Alleviation of symptoms may be attempted by reassurance, reduction of methylxanthine intake and treatment with danazol.
