What are fibrocystic breasts?

Fibrocystic breasts are characterized by lumpiness and usually discomfort in one or both breasts. The lumpiness is due to small breast masses or breast cysts. The condition is very common and benign, meaning that fibrocystic breasts are not malignant (cancerous). Fibrocystic breast disease (FBD), now referred to as fibrocystic changes or fibrocystic breast condition, is the most common cause of "lumpy breasts" in women and affects more than 60% of women. The condition primarily affects women between the ages of 30 and 50, and tends to become less of a problem after menopause.

The diagnosis of fibrocystic breasts is complicated by the fact that the condition can vary widely in its severity. In some women, the symptoms of fibrocystic breast condition can be very mild with minimal breast tenderness or pain. The symptoms can also be limited in time, usually occurring only premenstrually. It may not even be possible to feel any lumps when the breasts are examined by the woman herself or by her doctor. In other women with fibrocystic breasts, the painful breasts and tenderness are constant, and many lumpy or nodular areas can be felt throughout both breasts.

Is there a difference between fibrocystic breast condition and fibrocystic breast disease?

No. In the past, fibrocystic breast condition was often called fibrocystic breast disease. However, it is not a disease, but a condition. Most women tend to have some lumpiness in their breasts. Therefore, it is now being more appropriately termed fibrocystic breast condition. The abbreviation is FCC (an acronym derived from FibroCystic breast Condition).

Other names that have been applied to fibrocystic breast condition include mammary dysplasia, chronic cystic mastitis, diffuse cystic mastopathy, and benign breast disease (a term that includes other benign breast disorders, including infections).
