CYSTIC BREAST (FIBROCYSTIC BREAST, FIBROCYSTIC DISEASE)
Fibrocystic breast disease is described as common, benign (non-cancerous) changes in the tissues of the breast. The term "disease" in this case is misleading, and many health care providers prefer the term fibrocystic "change." The condition is so commonly found in breasts, it is believed to be a variation of normal. Other related terms include "mammary dysplasia," "benign breast disease," and "diffuse cystic mastopathy."
The cause of Fibrocystic breast disease is not completely understood, but the changes are believed to be associated with ovarian hormones since the condition usually subsides with menopause, and may vary in consistency during the menstrual cycle.
The incidence of Fibrocystic breast disease is estimated to be over 60% of all women. It is common in women between the ages of 30 and 50, and rare in postmenopausal women. The incidence is lower in women taking birth control pills. Risk factors for Fibrocystic breast disease may include family history and diet (such as excessive dietary fat, and increased caffeine intake), although these are controversial. Performing monthly breast self-examination and wearing a well-fitting bra to provide good breast support are important in the diagnosis and management of Fibrocystic disease.
